The animation sucked, some of the jokes in there were way to dirty for a supposed kids' film, and the script was all weird in my opinion. It amazes me that the trailer looked better than the actual movie. It also amazes me that they got an all-star cast, and Christopher Lloyd got such a minor part! C'mon, next time you get Doc Brown in a movie or something, at least give him more than 2 minutes of screen time.
