A perfect choice for the week between Christmas and New Year's, this movie is a delightful comedy about a thirtysomething man who befriends a 12-year-old kid, and one teaches the other one how to grow up (hint: it's not the kid who needs the lesson). Hugh Grant plays Will, the single, irresponsible adult in what's probably his best performance ever, and Nicholas Hoult is Marcus, who's a bit of an outsider and plagued by a manic-depressive single mother (Toni Collette), nursing suicidal tendencies. That sounds depressing, but the movie's both funny and poignant, and qualifies as a New Year's/Christmas movie because of several holiday party scenes. One of my favorites.
