I really loved this movie and I am not even a Diane Keaton fan! There are so many mafia movies like Goodfellas and Godfather that when a really funny mob comedy comes out like Plan B (or Analyze This) its a lot of fun to watch. This movie is a lot of fun and follows Fran, a bookkeeper played by Diane Keaton, as she finds herself involved with the mob in a lot of crazy situations. The story gets pretty wacky but is so much fun to watch. I was laughing out loud so many times and my husband was laughing too; that doesn't always happen. I would rate this movie about even with (or maybe just below?) Analyze This and definitely better than Analyze That and The Whole Nine (and Ten) Yards! The movie never gets boring and its fun to watch Bob Balaban, Burt Young (from the Rocky movies) and Paul Sorvino have so much fun working together. I give this one an A-
