A Bay of Blood (1971)

Forget the overrated John Carpenter, the hack Wes Craven, and anyone who had anything to do with any Friday the 13th film, because THIS is the granddaddy of them all. Only a master like Mario Bava could both create AND send up the slasher genre in the same film. The murders come fast and furious, while the soap-opera intertanglings of the characters is so hilariously complicated you’ll find your head spinning. And just in case you’re wondering whether Bava really intended this as a send up, just wait until the unbelievable ending. This is the only slasher movie anyone ever needs to see, and the news that it’s coming on dvd is cause for celebration.
