I mean, he might have liked it, it's not a bad movie and it's not a terrible adaptation of the story either. Probably would have to first explain the context of what the muppets are and a bit about the various characters to really get some of it though
J. Draper, London historian and, from what I gather, popular TikToker and YouTuber, has an interesting hour-long video comparing the Muppet version to the original as well as the various things that wouldn't necessarily be covered in the original, like costumes and how London looked. It's not quite a watch-along, but it does cover things in movie order.
I just watched this last night! Her takeaway is that is pretty good overall. Most of the costuming is pretty spot-on, even the muppets’, and she makes concessions for some of the things that aren’t true to the book since it’s ostensibly a kids movie and there is stuff that just wouldn’t make sense. A lot of the script is pulled directly from the book. Her big critique is about Scrooge’s childhood but she even finds a possible reason they decided to change that too. It’s really quite interesting! Also, as an American, I find it absolutely hilarious that she can’t comprehend that Americans don’t know what a Christmas pudding is. To us, pudding means something completely different!
It's the only adaptation that has Dickens himself portrayed. Admittedly I don't think Gonzo is an accurate depiction, other than the clothes, but it did allow them to put far more of the actual text of the book into the movie than any other adaptation, because they had a narrator.
