Muppets Most Wanted:
I found this a delightful movie. Again we have a frog who is unwilling to commit to Miss Piggy, but then another from; an evil frog, who is able to disguise himself as Kermit, while Kermit takes his place on the most wanted list. The evil frog is able to travel with the Muppets, while Kermit is in the Gulag, and work in a life of crime as he works his way up to steal the crown jewels. Kermit thinks he is forgotten, because the rest of the troupe do not realize he is missing, until they decide Kermit is acting strange. In the end, only Kermit can save the day.
This movie is cute, especially if you like Muppet humor.
