Resident Evil 2 ( i had a thing when I was 12 and played RE2 at night by myself, i nearly screamed everytime I saw a zombie back then anyway) The scariest part was the jeep crash so sudden.
The ring freaked me out a little espcially when u get a feeling in the back of your head that when u watch the video that they watch, the well, rabbit, woods etc that u will die lol
i know for what im about to say is going to be hard for some of you to understand but...
the only film that has successfully made me be on the edge of my seat throughout has been the remake of texas chainsaw massacre. i wasnt petrified by it but i found myself feeling uneasy during some parts. i thought the exorcist was boring and the original tcm was boring and just not scary.
the camera angles and set designs used is what i think made the remake a great film. im not gonna say it is crap and the originals better just because that is mostly the case for remakes. but i really think the remake was justified. it was also quite original considering it was a remake!
