This is a mostly well written, acted, and nicely filmed wacky movie.  There is nothing deep here just a few bumbling young robber friends.  The  problem is only one of them wants to really be a great robber and he is a  complete moron who can't even keep a job mowing lawns.  Another is just  trying to impress his jerk brother and the third just wants to be a good  friend and find a chick to love.
