YMMV: Reazione a Catena
Vindicated by History: Caused a lot of damage to Mario Bava's career due to it's unflinching depictions of carnage. Christopher Lee reportedly even walked out of the screening disgusted with the violence. But, it's now regarded as providing the blueprint for the 80s Slasher Movie. A lot of it's kills have been imitated, ripped off, spoofed and homaged most notably by Friday the 13th Part 2 but this one still retains it's power to shock.
