The other problem I think Tim Hill had was that it was his first motion picture where he was used to directing Saturday morning schlock for Nickelodeon. If you look at MFS, it moves way too quickly. He jumps form place to place as opposed to waking time to establish your villain, give us a reason to care baout Gonzo's plight, etc. I found I was tired about half-way through the film. There really aren't any scenes in that film that last more than 2 mintues or so. You can't direct a film with the sensitivities of a Saturday Morning cartoon, it just doesn't work. Whereas Gilliam and Jonez and and even Frank Oz and Brian Henson are storytellers and will take the time to set-up the scene and the characters and really tell a good story. Of course Frank's real strength is in establishing characters and telli a good character motivated story, Brian (as I mentioend eralier in this thread) is marvelous and getting what he wants out of a shot and setting the tone and mood of a piece. Gilliam is good at keeping a story movie and keeping the humor fast, but also takes a great care and into making sure what you see on the scene 'is just right. If you watch the Special edition DVD commentary on Monthy Ptyhon's quest for the Holy Grail, you'll hear John Cleese actually complain quite a bit abou this. I think Jonez is just weird and has a way of making his audience say "Whats did I just watch."
If you look at Muppet films of the past, 4 out of 6 have been directorial film debuts. So what makes Tim Hill's different form the other 3? Well, Henson, Henson and Oz had all worked with Muppets before and were aware of the technical difficulties and were in famliar environments. Tim Hill really took on a baptism by fire. I just don't think it worked vary well. now I'm kind of babbling and I tihnk I forgot what my point was, so I think I'm going to go have dinner now.
