There's a punk-rock attitude, clearly, to 'Hated.' There's even a punk-rock attitude to 'The Hangover,' I think. We start the movie with a Glenn Danzig song.
There's a darkness under 'The Hangover' because ultimately there's a missing person and it's not really that funny. There's a sort of darkness under it that I love, and still people are laughing as hard if not harder than they did in 'Old School.'
