Can't remember the last horror film I saw that didn't make me laugh.
Is House of a 1000 Corpses or Devils Rejects class as horror?
Recently watched The Borderlands, thought the start was a little slow, the middle excellent, the end died on it's arse, was expecting more.
EDIT - Scream is fantastic, one of my favourite horror/slasher films. The sequels tho were poor, the humour in the original was subtle, they attempted humour in the sequels.
Anything with clowns or young children, particuarley Chinese kids sitting in lofts (The Grudge) is fucking horrific.
