Okay, so having said that... there are a lot of versions of A Christmas Carol, and I like an awful lot of them. This is the only version that I watch every year, though, and it has my wholehearted endorsement. Although, I suppose if you don't like the Muppets, you won't like this version. (Are... are there people who don't like the Muppets???)
My one quibble here is with the DVD version released in 2005. It features both the complete full screen version, and a widescreen theatrical release with a scene cut. (The scene where, in the past, Scrooge's fiancée bids him farewell for the final time.) The movie makes sense without it, but the scene loses almost all of its impact (yes I'm talking about a Muppet movie) without the farewell song.
So you can watch the movie with that scene in full screen, or without that scene in widescreen. I hope they'll do better and include it on a bluray release in the near future. In the meantime, if you want this and you haven't bought it, it might be worth waiting to see if another release is around the corner. (Or you might not have the same little quibble that I do!)
(Also, I will never get tired of Michael Caine saying, "It's Fozziewig's old Rubber Chicken factory!" with a straight face.)
