This is one of D'Amato's better horror films. Not so heavy on the sex, but definitely heavy on the gore. Supposedly he got in trouble upon this film's release because they thought he used real cadavers in the dismembering/disembowelling scenes. They do look impressive!
I'm sure Ruggero Deodato makes movies just to shock and disgust people. This one is no exception, though it's not nearly as offensive as "Cannibal Holocaust". If you like rape and murder, this film is for you.
