I agree the concept was good but it was too long for such a simple story (or at least I didn't experience it as thought provoking stuff). The execution was ok but nothing extraordinary. There is way sicker stuff out there I think.
Climax seriously? I wouldn't even call that horror. Sexploitation perhaps but not horror. Makes even the 60s roughies look good. Oh you didn't like Raw, well I'll erase that from my list, i'll try not to repeat the ones already listed here.
Well I'm too lazy to shift out the 10 best but I'll do an effort not repeating the ones already listed by Box and peep even though only I Spit on your Grave and Raw could have made mine.
