The scenes used don't really hold together as the premise for a false trailer (e.g. 'Shining', 'Scary Poppins'), but fuck if I'm going to give 'the Wicker Man' anything less than all my stars.
This one's pretty ambitious -- punching an old lady normally doesn't fit into light-hearted romps -- but what would be the point if they didn't use the really good scenes? Five stars easily.
