Wow, this thread has me bummed . . . My son wants badly to see this movie because he and his sister both absolutely adore the cartoon. When I had first heard about the movie I was hoping they had done it "Lord of the Rings"-style and done about a 6 hour movie they would show in installments . . . instead it sounds like they tried to cram it all in to one relatively short movie. Too bad.
I hope in a few years some better film maker decides to do it correctly. I've not seen all of the cartoon, but what I've seen has some endearing qualities. It's a shame it wasn't given justice.
