Which is hilarious by the way. Toughpigs gave it a good review, which means at least the fans will like it. The two good reviews are glowingly positive, one of the negative ones is mean spirited (probably some indie news paper or something, they love to be jerks) and the other two didn't get it. Hopefully we'll get more fair, well written reviews once the film hits.And the main criticism is that Jason and Amy aren't in it, which is completely dumb.
And if it doesn't, the heck with them. Like I said, GMC got crappy reviews from a respected critic. And that's one of the 3 gold crowns of Muppet movies in the fandom.
