Black Christmas unless the word "cunt" constitutes gore.
and if you're looking for the goreless flicks you've prolly been bludgeoned with with "Men, Women and Chainsaws" and should try and slip some shit past the "intellectuals".
Psychological Horrors? You can't go past Maniac, Henry: Portrait of a Serial Killer, Deranged or Crazed (<----- the most tastefull of the bunch). Total descents into madness with out some slithering porno shakesphere tongue fucking bullshit.
But from what you're talking about you wanna check out Manhunter or Dressed To Kill.
How about Raising Cain? Easily the most overlooked flick for this kinda shit.
Body Parts
The Hitcher
Near Dark
(...... fuck check out Eric Red in general I haven't for awhile there's bound to be a bunch of dope shit with his name attached).
and if you're from NZ you might be able to grab a copy of Bad Blood (not a horror flick but definatley fits in with these kinda flicks).
But whatever. Most of the goreless/less exploitative shit is a thriller or drama flick that the horror kids sit in front off (and enjoy 9/10 times).
