Yes, it’s dated and cheesy and the special effects have been far surpassed, but there will always be something about physical puppets well-performed that’s inherently compelling (even if not convincingly realistic) – and director Jim Henson’s fantasy has some of the most imaginative and inventive ever seen. The script by Terry Jones is clever, even though it looses focus towards the end and has an inexplicable and unsatisfying ending. But for sheer strangeness, the image of David Bowie singing in a castle full of Muppets is hard to beat.
