No question, The Exorcist.

Thats not horror is it ?

noes1 or friday13th

1. The Shining ('80 version)
2. Cabin Fever

Not horror, but very good movie : Ichi the Killer

my favorate is halloween and i strongly believe that it is the best horror movie of all time but i'll have to say it's a tie between halloween and the shining because halloween is the original slasher it had the soundtrack,the classic pov shots that you had'nt really seen before,and the Dr. Loomis charactor is just great. on the other hand you have the shining which also had a great soundtrack and a script adapted from stephen king is always going to be good,the amazing acting from Jack Nicholson and who can forget that classic line which i've used for my signature. these are two classic horror films that i believe are tied at the top of the list of course with texas chainsaw massacre a extremely close second.

William Peter Blatty's original Novel, inspired by true events in 1949, I have read twice. He wrote the screenplay that William Peterson directed and fought with him so much about. Well, whatever cut you see, although Mr. Blatty's adds much cohesiveness, it is the apex in film of philosophical doubt. For that is really what The Exorcist was about, having doubts about one's religion, doubting one's own faith! It is not really a horror movie or Novel, it is much more intellectual than that. :)

Dawn of the Dead and The Thing(the re-make).

Bless you all!!
