The Muppet Christmas Carol marked a key transition in the life of its parent company, Jim Henson Productions. It was the first movie released after Henson’s untimely death, and represents a radical departure from previous Muppet films. They based it on previously existing material, for starters, and the Muppets played specific characters rather than versions of themselves. It also featured a live performer (Michael Caine) front and center: a risky move since his costars have a tendency to upstage everyone. Despite those changes, the film itself holds up quite well, and its release on Blu-ray aptly demonstrates why. Hit the jump for my full review.
