Muppet Wizard of Oz. To say that it defied the very nature of suckage would be useless, because the movie previous to it had already done so; for example, it featured Steve Irwin hunting down and drugging Frosty the Snowman. This, this is what you get when you've taken something seemingly immune to suckage, and drag it kicking and screaming into the dark heart of the suckage substance.
If you ever hear that someone near to you is going to put the film in front of kids, take every step you can to have it destroyed before that can happen. Apart from the shenanigans with the Muppet Christmas Carol DVD, there can be no greater insult to Jim Henson & co. than the Wizard of Oz film.
