What are some of the most realistic horror films?

Human centipede. jk

Texas Chainsaw Massacre.
Psycho.
Last house on the Left.
that one movie about the guy who inspired the Texas Chainsaw Massacre (based on a true story by the way).
and....that's all I've got.

Well maybe not the graphics but Scream because i hate screaming into the T.V when the people do something completely stupid and in this movie it was like they were actually aware of what not to do and the killer is a serial killer not no ghost or something unrealistic.

Like a Dagon... Kind of thing? "

Scream and Psycho comes to mind.

Wasn't he wearing a vest, though? Or was that the third?

One of the 1,000 ways to die is by having a nightmare.

Yeah, a heart attack in your sleep caused by a bad dream. It's like the pokemon Gengar used Dream Eater on you, and you die.

Realistic in your face, literally.

well from what I have seen in Florida... we have some real Sea Monsters down here 
lol "

the movie Paranormal Activity seems very realistic.. it made me paranoid for a while.. lol..

Not that Zombies are realistic or anything (yet), they can still terrify me.

" @Edamame:  I'll give you a summary of each (although I've never actually seen any of them).  Texas Chainsaw Massacre (original or re-make) is about a group of kids traveling along the Texas countryside when they pick up a hitchhiker (depending on which version it is, the hitchhiker is Leather face's brother in the original, and a girl in the new). Any how, the hitchhiker does something to get the kids to go for help inside of the murderer's house. From there, they're hunted down, some are slaughtered, then eaten. If I'm right, only one person lives in the story.  Psycho is about a mad-man who owns a hotel, and , as one could guess, he kills his victims from there.  The one about the guy who inspired TCM was based off of a true story about an actual madman.  and Last House on the Left (either version) involves a group of killers who rape and kill one of the two girls. She makes it back to her house where she tells her folks what happened. From there, I believe that the parents get their revenge.   Some one please correct me if I'm wrong. "

Any of the Saw films can be thought as realistic.

Some movies that seem realistic to me are....

1. The Skeleton Key- I live in new Orleans and I can tell you that Voo Doo and Hoo Doo are very much real...I've seen cases of these practices, but I don't dwell within these two...Voo Doo is a religion where else Hoo Doo is "Magik".....
2. The Last House on the Left- This movie seems more realistic in a sense of human nature...Its in our nature to seek out revenge...some take it to extreme measures...Its possible that people would hurt those who have hurt them as they did in the movie....an eye for an eye....
3. Psycho- There are a lot of sick people in this world...Its possible that a man, who has went through a lot in his childhood, can grow up to be a psychopath and a schizo....
