A lot of my favorites may not be considered straight horror, since I'm really not a big fan of scary movies. In no particular order, let's see if I can make it to 10:
Fright Night (I don't even know if it needs saying, but this is not the remake) Dead Alive/ Braindead Phantasm (the Tall Man is my favorite horror villain ever) The Monster Squad Alien The Thing (the remake, but not that remake) The Frighteners Hellraiser 1/2 Aberration (Not a good movie, but maybe I just like horror films shot in New Zealand)
Edit: I feel ashamed for realizing I left out The Shining, or really anything else from the works of Stephen King, but this is my list and I'm sticking with it.
Wait, I voted for the Raid, but screw that. Jeff and Ryan need to sell the raid idea to corporate as a company write-off. If he did end up using the proceedings for the raid, I'd go into Super Potato and buy out the entire PC Engine section.
