In the theater:
A History of Violence
This was full of graphic sex and ultra-real violence. Ed Harris was good as a really scary guy, but otherwise I was generally underwhelmed by the acting - especially from William Hurt (whom I normally like).
Rental:
The Family Guy - Stewie Griffin: The Untold Story
While not as constantly funny as I'd hoped, there were parts of this movie that were so funny I was gasping for air I was laughing so hard. I highly recommend this for anyone who likes the Family Guy, the Simpsons, or Futurama. I think my favorite character is the dog.
