Hilarious, intelligent, bittersweet and deeply touching comedy about a teenage girl who gets pregnant and decides to give her baby for adoption. This is an amazingly surprising film, which subverts every imaginable cliché on this subject (usually after suggesting a cliché, but then pulling the rug from under the viewer's feet by avoiding it altogether). Ellen Page is amazing in the title role. The unbelievably clever script was written by former stripper Diablo Cody.
There is a great review of the movie by Dana Stevens in Slate.
