High Tension was SO GOOD. When the twist happened at the end I had no bloody idea and was totally WTF MY HEAD OMG
There needs to be more films like that. I like a good slasher but HT made me :mymelomfg:
As for Cannibal Holocaust, it isn't a very horror movie type of thing. You may not like it, tbh. If you are going to watch it, watch it like 'day of the woman' in that it is historically relevant.
The only scene in film history I've watched that genuinely scared me is [get this]:
(SPOILER)the painting that moves in the hotel: in the mouth of madness. After seeing the first scene I could not look at that painting ever again. WTF!
