Your favourite horror movies?

pieces (1982) one of the silliest, most absurd, but also entertaining slashers.
the first time i watched it, i was pretty baked, & laughed so hard at a scene featuring a 'tennis pro' trying to hit a ball i threw up on my sister's living room carpet.
makes little sense, but in the fun no-sense making way. and lots of attractive women. maybe the best looking slasher cast i've come across so far.
