Form - Extreme eye closeups, first-person camera, all the things that make both slasher films and Fulci films great rolled up into one. The actual photography isn't really as masterful as that seen in the Beyond or even House by the Cemetery, but it's still tasty.
F/X - Mostly peoples necks getting chewed on by the titular anthropophagist (anthropophagoer? anthropopaguy?). One scene has a crazy fetus devouring, but other than that, nothings too grotesque.
Acting - Nothing bad. The blond seer girl is great and the killer is just ridiculous.
Mise en scene - Goo, skulls, creepy mansions, everything hits the nail on the head.
Quotables - "Hellll yeAAH".
Cool stuff - Chocked full of it. Great gore effects, some good build-up, a quirky soundtrack. The ending is absolutely phenomenal, nonsensical, and gruesome. At the same time, it was the only way they could bring the repulsion to a fine point before cutting the film off.
