From a technical standpoint Muppets from Space was the worst reviewed and poorest box office performing film of the franchise. It also cost twice as much as Muppet Christmas Carol, yet had no original music. The tug-of-war between the studio and the writers killed it. I actually cried in the theater because it was so dreadfully bad I believed it had the ability to kill the Muppet brand. It did harm it – a lot!
Fortunately many younger fans saw enough spark in it. That push helped the film gain some status on the home video market. It plays a lot better on the smaller screen. Portions of that film and the characters solidified with younger viewers and I recognize that film is responsible for some of today’s fans.
The puppets and musical numbers were pretty good in Swamp Years, but the human actors and writing never really transcend kid-vid quality. I don’t think Sesame Workshop would have run with such a rather juvenile script. Jim Henson himself cancelled the much more developed and witty Little Muppet Monsters program after only three episodes. I can’t see how he would have approved the outcome of KSY.
Oz didn’t quite get things right either, but there was enough layered humor to keep me interested. The Muppet projects used to have something in them for everyone. I missed that until recently. That's what makes me so froggin' excited.
