Basic undead types in fiction

Revenants

A person who's returned from the dead but there isn't necessarily any rotting, meat or blood lust or even immortality. Revenants are the basic back in the flesh undead and are the historical representations of both zombies and vampires, depending on their extra characteristics. The are often associated with or from Romania. Sometimes revenant is just another term for undead.

Zombies

There are various subbranches and causes but zombies are the almost or completely spiritless dead with minimal brain function and bodies that rot. Originally zombies were commanded by their summoners.

Vampires

Either always a vampire or a human turned. Vampires are technically immortal and drink blood. They can be killed in a variety of ways but if left alone they will not die unless exposed to the sun. Even refusing to eat is unlikely to kill them unless this is specifically referenced for a plot.

Ghosts, phantasms, and spectres

These are those who return or remain in spirit only while their bodies are buried or cremated as usual. Sometimes cremation or a proper religious burial is written in as a way of destroying the spirit or sending it on to the afterlife/putting to rest. These are less likely to be violent or able to manipulate the physical but can be either benevolent or malevolent. They range from see-through to clearly visible but none have a physical presence.

Shades, spirits and devas

Shades are ghosts acting under the command of their summoner. 

Poltergeists

Violent malevolent ghosts able to manipulate the physical. Spirits and devas have a little extra ability in the way of magic and are a good choice for placing within a body, if needed, as they have some control.

Ghouls, ghasts and wights

These are more substantial than ghosts or shades. They are vicious and malevolent spirits who have a strong physical presence. Their touch drains the energy of a person and both ghouls and ghasts tend to tear their victims to shreds. Wights are related to the ghouls and ghasts, they have claws that suck the life out of all living things. They have the ability to eliminate a person's memories and skills, leaving them living zombies or like newborns. All are quite capable of working in groups or at least congregating. It is often the case in modern fiction that ghouls have a physical form much like that of zombies but stronger and less human.

Wraith and Hraithes
A wraith is often a ghost or image of someone seen shortly before or after their death. They can also be depicted as strong and lasting spirits who suck the life from anyone who touches them. A hraithe is the spirit of a vahnatai mage reluctant to move on or rest. The hraithe is often jealous of the living and still magical to a certain extent.

Walking skeletons and vahnavoi

Walking skeletons have basic human strength while vahnavoi are imbued with the extra strength and skills of a sword fighter. They are usually summoned from the grave just as zombies can be.

'Frankenstein's' monsters 

Scientifically reanimated and stitched together monsters that resemble humans, they often have the thoughts and feelings of young children or the mentally disabled due to brain transplant procedures and oxygen deprivation at death. They are usually called 'Frankenstein's' monsters although the maker may change.

Mummies

Bodies missing parts and often skeletal, mummies are much like zombies except they've been dormant for a long period of time, they don't bite and aren't made from contagion but may be created by a spell, may act upon a summoners orders or carry out a curse. They do not rot as zombies do but rather decay as though still in a dry enclosed climate.

Magical reanimations

For these, the or a spirit is returned to the flesh. Problems usually occur, such as the body rots or the spirit fades or can wander. Spirits other than the original body's may be used, even demonic spirits. The magic used is often depicted as black or at least dangerous to the practitioners.

Rosy's scrawlings on Shinrei Tantei Yakumo
This manga is slow paced in comparison to many other stories containing ghosts or focusing on hauntings and it is so because the stories are approached from a detective angle rather than a thriller or suspense one. This means that the slow picking up of clues and the pondering of spirit problems takes precedence to running into a building and sending all the ghosts over to the other side, whether that be heaven, hell or some other derivative of the other side. There is something rather engaging that comes from this slow progression in the story line and that is the slow building of disquiet and tension. Nowadays it is more common to find oneself slammed into a tense situation, complete with battles and gore, right from the get go as this is what is deemed the most engaging, style-wise at least. Here though, you'll see an ancient form of story telling only recently left for dust return with gusto. Here are ghost story told in whispers and with a subtleness that will leave your skin crawling as you wait for the final scare, knowing full well it is coming but not being able to do anything but to progress onwards to find out what it is all about. As such, you'll find yourself thoroughly addicted and pulled through the story arcs, unable to stop reading until you reach each ending. Personally, this addiction became bad enough that I couldn't start a new story arc until the entire editions for each had been uploaded (I now have another arc to enjoy after reading this).
Yakumo is a quiet man, sneaky and amusing at times, who likes to put on a dramatic front in order to encourage business. It also heightens the atmosphere as well as the hammishness of the old melodramatic detective/psychic image. At first, I found his melodramatic nature a little irritating but I quickly learnt to smirk and laugh at it. You really don't have to take it seriously, as even he doesn't at times. Otherwise, Yakumo is a little rude, a lot abrupt and rarely speaks when he doesn't trust someone. Only those close to him get to see anything of him but his facade of psychic. He's also rather clever.
His character is also balanced out nicely with that of Gotou who's openly abusive and brash and more the stereotypical rough detective than Yakumo is, and that of Ozawa Haruka who's your average open and capable college girl except with a regretful past and a lot of misery. Gotou provides detective and police support, manning what is essentially the unofficial X-files wing of the department, while Ozawa provides more personal support and allows Yakumo to open up, speak and sometimes even do things that are personable and nice.
The three of them, sometimes joined by others, join together to discover the reasons for the hauntings and dispel the ghosts. The ghosts are often menacing but there are a few who guard the living and help the three to stop the more vicious ghosts. In all, the most interesting aspects of the hauntings aren't always the hauntings themselves but rather how they came to be and luckily for us, these stories are explained in full.
The art of Shinrei Tantei Yakumo is by Oda Suzuka. It is full of shades of grey and has a certain graininess to it that emphasises the detective aspects of the story. The ghosts are mostly boldly drawn, often inky black, as is the new trend for Asian ghosts likely to cause harm. There are a few white ghosts, their colour reflecting their innocence, but there aren't any of the more traditional styles. This helps to make Shinrei Tantei Yakumo appeal to young readers. The most amusing part of Oda Suzuka's are is the darkening of Yakumo's dramatic sentences. It is spot on for carrying the mood and makes me smile. All in all, the art is appealing, subtle and well done.

I'd recommend this manga to: those interested in supernatural detective stories, ghost stories and psychic stories. I'd also suggest it to anyone who hasn't as yet tried any of these sub genres as Yakumo is one of the best fictional psychic detectives about, even if he likes to ham it up on occasion. 

Notes on manga reader sites
The quality of manga readers can vary. The uploads are often done cheaply or as a serious hobby by a collective. Be aware that sometimes licence hasn't been given but the sites noted above, Manga Fox in particular, are extremely careful about adding and pulling mangas according to license agreements. So you shouldn't have to worry too much about the material being pirated. There are also translated works and non-translated. Amongst the translated works you will find that the quality of translation may vary according to the skills of the translators. Usually the works are perfectly readable anyway, with only a few added or dropped words or a word in the incorrect tense or with/out plurals. But sometimes the text becomes gobbledygook. In which case, either seek another version or give up and buy an official copy once a printed translation comes out. The other issue of note is you may need to expand the screen to read the text easily as sometimes the scans are minimised a little.
I find that if a page doesn't download properly or some other issue occurs (too slow or someone ordered the pages incorrectly etc.) with one reader then skipping across to another reader and picking up where I was is quite easy and rarely annoying.
Otherwise, enjoy and watch out you don't get too addicted you forget about the necessary things in life.

Best fictional Asian ghosts in the movies

European ghosts and Asian ghosts differ in modern types and in ancient types, just as the concepts of what demons are and their forms have differed between these two major cultural systems over history.There are, of course, a great many similarities due to general agreement that ghosts are disembodied souls or spirits but from there the differences compound. Ghosts, spirits and demons are far more closely related in Asian mythologies than they are in European ones which tend to set demons aside as separate entirely entities from humanity.

I could go on, but suffice it to say that Asian ghosts deserve a post all their own for best fictional Asian ghosts as these ghosts have different qualities, mythological backgrounds and causes of creation. Different stylistic trends apply when writing them so they should be viewed differently. Sadako stacking up against the old ball and chain toting convict doesn't really work, one being an echo and the other being of full character and vengeful motivation, not to mention very close to a demon in nature.

As to the movies condition, I find ghosts to be at their most effective when seen and heard rather than read. So for fun I decided to look into movie ghosts.

Sadako from Ringu or The Ring
The best of all the long hair and vengeful female ghosts, although there are a few very spooky rivals.

The cat/kid hybrid from Ju-on or The Grudge
He is two spirits combined to make one ghost. He's quite unique in this respect.

The woman of the snow from The Woman Of The Snow in Kwaidan/Kaidan

The first wife from Black Hair in Kwaidan/Kaidan
Note: The stories that make up Kwaidan are very traditional in nature but in them you can see the roots or movies like Premonition, Ringu, The Wig etc. Kwaidan is sometimes acclaimed a classic and sometimes denounced as a right bore but either way you feel Kwaidan is highly influential. Kwaidan is made up of films that bridge the traditional and the modern, the stories old and the soundtracks and filming new.

Main female ghost from A Chinese Ghost Story, known by several names. (Above is Nip Siu-sin from Ching Siu Tung's A Chinese Ghost Story, 2011.)
She is a ghost who makes a sucker out of the one who loves her for quite some time and in the end she gets what she wants. His love for her is real but I'm not too sure about the other way round as she wants too much else and gets him to seek it for her. Either way, she and her struggles are the basis of this classic story (based on a story written in the17th century).

Fleur from Stanley Kwan's Rouge
Cheated of the ending she desired with her love she goes searching to find out why he left her to die alone. She is a mix of love, hate, revenge and loneliness and as such has more personality than most ghosts.

Mitsuko Kawai from Dark Water
Based on a short story so some see this movie as quite spare and lacking but that is sometimes what happens when you expand a short story to make a long movie. Still, Mitsuko is an impressively scary ghost who just wants her mother. Or a mother.

The wig from The Wig or Scary Hair
The wig is made from the hair of several dead women so it can be seen as cursed more than a haunted object but either way, the wig is often ghostly in its actions. 

Tomie from the Tomie series
Although never really seen as a ghost as she's constantly possessing people in an attempt to be regenerated or reborn. Tomie is almost a demon in nature and definitely so in personality. Tomie the movie series springs from Tomie the manga.

The ghost boy from Silk
He's a simple and elegant kind of ghost who's very angry at his mother. He's interesting less for his motives and more for his portrayal, which is closer to modern western ghosts than anything else. He's a remnant spirit who often repeats his actions and has a single motive. But there is still the base emotional drive that dominates the ghost to the point where all but the original history of the person he was is lost, marking him with some classic Asian ghost characteristics. He's a hybrid and his status is reflected in the movie style, which resembles to some extent movies like Paranormal Activity.

Natre from Shutter
The psychological weight of killing someone becomes all too real as Natre sits on the neck of her killer. The moral to the story isn't overdone as it is never directly pointed to but at the same time the moral is quite understandable across all cultures as it isn't related to minor or localised social issues but rather major ones.

The ghost daughter from Re-Cycle (named at the end)

Re-Cycle as a movie has some issues, though none that would ultimately spoil the movie completely, but the ghost daughter (main character doesn't know of the relation until near the end) is an excellent addition. The daughter is helpful even though she has much to be angry about and in being helpful she becomes a person more than a ghost.

The slit mouthed woman from Carved or A Slit Mouthed Woman
Based on traditional legends of a Samurai slitting the mouth of his wife because he suspects her of cheating. She is more shock value than anything else but by discarding creepy suspense for slasher type horror, she is rather original amongst the long hair female ghosts.

Ling from The Eye

This haunting is one brought on by misery and a need for forgiveness rather than revenge. The ghost of Ling is more concerned with getting the one now using her eye to do her will than anything else. She appears by revealing places significant to her as often as she does in 'person', giving the impression that she is as much a residual memory passed to the eye's new owner as she is a ghost.

Su-yeon from A Tale Of Two Sisters

It is hard to tell if she's a ghost or a figment of Su-mi's imagination, which is a mark of a very well written ghost story. Su-yeon as a ghost, if she is one, does little but Su-yeon as a figment of the imagination does much. The problem you're left with at the end is: are all ghosts just a figment of our imagination despite what we see and hear?

Pim from Alone

Pim is a ghost less bent on revenge and more on curtailing her sister. It is rather hard to tell who is who between these sisters through most of the movie (even though you do guess as to what's happening) but it all becomes clear in the end.

Kim Tae-yeon from Cello
Vengeance is they name. Kim Tae-yeon is pure hatred and vengeance which isn't what sets her up as a well written ghost. What does is just how successfully she gets her revenge.

Faceless/Orphaned Girl from Cinderella
See her face above. On the wrong girl. She just wants her face back, damnit.
