I noticed that this was actually based on the book (VERY loosely) rather than the Judy Garland film. There were some things thrown in from the book maybe just to prove this point, such as the Tin Man's backstory (of course, it was Gonzo and the chicken in this!) and the hat that controls the winged monkeys. Regardless, it's an appalling film, well it's not even a proper movie, just produced for TV. It had very little of the Muppets magic. It isn't a wonder that Frank Oz has left the Muppets.
