This is one of those films that's sweet and funny, and just a joy to watch. I was told that I'd love it, and somehow knew that I would, and I did. I love how such unrealistic, exaggerated characters always feel so real (cf. The Royal Tenenbaums). There's really not much more I can say about this film, there really isn't that much more to analyse. It's kind of a character study, I guess.
I'll put the third film in its own entry, too, so you can comment about this if you like, without accidentally reading any spoilers.
