Are you familiar with the work of his son, Mario Bava?

No, but I'm familiar with the work of his son, Lamberto Bava. :D

All kidding aside, Macabre is the kind of fucking insane, that-cannot-possibly-be-based-on-a-true-incident movies that was, of course, based on a true incident involving a woman, a murder, and her husband's severed head in a refrigerator.

Italians, man...like, WTF? :D
