Critic Reviews for Knife+Heart
This is basically a slasher. A gay, porn-fest of a slasher featuring Vanessa Paradis and a host of others with very limited on-screen time before they come a cropper at the hands of a queer version of the grim reaper - and one who has an impressive imagination when it comes to thinking up ways of dispatching people! The story is a completely ridiculous but it can be a provocative one at times too, whilst generally holding together in an entertaining way as it builds to a slightly daft denouement that - appropriately - takes place in what looks like a brothel... Camp as a row of tents, but it features an always welcome Félix Maritaud and I quite enjoyed it.
