Mind numbing would be a compliment for this film. Children's films should entertain kids and make them want to talk about the film, not what they're going to do after it's over.
For anyone over age ten, this is insulting to the intelligence. Huge plot holes, kids behaving smarter than their age, and adults who are incapable of the obvious help you forget the insulting dialogue. I almost felt sorry for Dennis Weaver and Joe Piscopo being a part of this.
I had to use this film on DVD with subtitles to teach English to my Japanese students; they were 11 and found this painful to watch. Clearly it's not for anyone smarter than "Zike" or "Spider".
Exactly what was the point of the horse rustlers who never appear again? At least in Monty Python's "Life Of Brian", the UFO scene was put in for humour. And _do_ horse rustlers really exist in this day and age?
