Ok ! If you are really looking for horror and thriller flicks , then must go for The final destination, scream 4 , rubber and bunker of blood movies surely and you will get a new world of horror there .
Here the list of some good horror movies are : The Crazies, Daybreakers, The Wolfman, Piranha 3D, The Last Exorcism, Let Me In, Paranormal Activity 2, Frozen, Buried and Shutter Island. These all the movies are too horrible and interesting.
Almost all the peoples like to watch horror movies and here some of good horror movies like: Evil Dead, Arachnophobia, Book of Shadows: Blair Witch 2, The Blob, Event Horizon, Dawn of the Dead and Dawn of the Dead.
paranormal activity 2 first to understand story than 1 and now 3 is coming out in oct, grave encounters , quarantine not 2 it kinda sucked , scream of the banshee , final destination 1 2 3 all others sucked , i didn't really think any of the dawn of the dead movies were creepy sorry , the decent and part II were really scary and good haven't seen a more creepy and gory movie since that one i can tell you that much must see , watch all grudge Japanese versions (ju-on_) 1 2 3 all of them are better and more scary than American crap
The Exorcist, Evil Dead, Season of the Witch, Vanishing on 7th street, 30 Days of Night: Dark Days, All About Evil, Black Swan, The Crazies and Daybreakers. These all the movies are best and too horrible.
According to my choice in horror movie, I like to watched The Shining horror movie over and over time. It is most scariest movie of all the time. The Ring is also very nearer to horror and my favorite scary film.
