For a movie on a planet of idiots, I enjoyed this extremely. Outstanding performances by Jon Lovitz and Jeffrey Jones and even more-so by Eric Idle with is memorable line "I'm the most intelligent one here and I'm an idiot!" It was also good to see the Stanton Brothers [Don and Dan] together in this film. They are certainly moving along from their Gremlin 2/T2 spots
I found the little mushroom guys in the sewer reminding me of Super Mario Bros. and such, but found this film extremely enlightening. If you have the chance, I highly recommed watching it, it is so choice
And finally, my favorite scene is when Jeffrey Jones is first thrown into the dungeon and encounter that funny rat
