Some parts very funny, some parts just ordinary homegrown American all-that-is-vaguely-taboo-is-fun (hence the ass-poking scenes), some grossness thrown in and, last but surely not least, a famous actor well-known for his TV-series to which some jokes can be directed. "Evolution" is a bit strange, a combination of fun and not so fun that just doesn't really land very well and that has an extremely silly ending. Stupid characters and some redundant along with a dimwit script (I mean the periodic table deal, what the hell is THAT!?) - but sometimes it manages to be very funny. I have a soft spot for Duchovny, so lets hope he finds better movies after this one.
