Armie Hammer and Leonardo DiCaprio in J. EdgarJ. EDGAR

Pretty much everything that's bothersome about director Clint Eastwood's biographical drama J. Edgar is only bothersome for the movie's first half hour. That may sound like a lot of time spent bothered. But the film does run 135 minutes, even its weakest moments are by no means awful, and in the end, it emerges as a really fine work with a really fine central performance. So as a nod to J. Edgar (the movie, not the man), let's just get it out of the way and address its failings at the start.

Jason Bateman and Ryan Reynolds in The Change-UpTHE CHANGE-UP

The Change-Up, in which Jason Bateman's discontented husband and father magically swaps bodies with Ryan Reynolds' perfectly contented slacker dumb-ass, is an appallingly smutty and juvenile slapstick. In the segment that finds Reynolds (in Bateman's body) preparing a late-night feeding for his pal's infant twins - with one tot seen playing with butcher knives and the other reaching into the blender and sticking his tongue into an electrical socket - it features one of the most painfully unfunny scenes in cinema history, and I'm not excluding any given scene in Sophie's Choice or Schindler's List.
