I thought the movie was good... not great. It was totally worth a trip with my girls to the theater all dressed up and out to have a good time. I would NOT have tortured my husband with it though.
It was a little long, but I really didn't notice other than needing a potty break. There was no real plot to speak of, it just kind of seemed like a longer version of the show.
Overall, totally worth it for me and my girls. We laughed and had a good time. Do not make your husband/boyfriend go see it though - spare him.
