This entry from Jim Henson's crew basically kicked off the aforementioned trend of 80s kid-oriented epic fantasy films. The film is done entirely in puppets, causing some uncanny valley problems, and has a pervasively dark tone, probably not what you were expecting from the creator of the Muppets. I feel that the world and backstory is poorly developed: too vague in most places and too orderly and cookie-cutter in the places where it's not vague. In short, the story writing is appropriate for very small children, which hurts the film's attempts at having an epic scope. I wish I could like the film more, but the final result just isn't interesting enough. Score: 2 stars out of 4.
