One and Two were funny. Three is not! If your kids are really desperate to see it in the theatre, go to a cheap matinee. Otherwise wait for the video. If the producers keep going in this direction, Four will be released straight to DVD. That said, there's nothing really objectionable to the movie. The adult jokes (naked shrek, pot smoking, etc) will go over the heads of the target audience BUT probably not their pre-teen siblings. Be forewarned.
