Our Idiot Brother is a simple minded comedy that never hesitates to use Paul Rudd's comic sensibilities to their full potential. It's a "cute" movie that features a strong message of family, forgiveness, and the strange bond between three bull headed sisters and their naive brother.
While it's not going to win any awards, it's a good enough comedy that never crosses the line in to profanity or gross out humor. I enjoyed the movie enough to give it a recommendation based on it's innocent approach and Rudd's perfect portrayal of a true idiot. Rent it.
