I'd probably have to see that overblown excuse of a Christmas special to get a real feeling for what it is, but the plot synopsis, trailers, and overall character looks just give me a total ick. From what I understand the movie's about the clumsy brother who's not as valuable as the others but somehow manages to save the day by "thinking differently." Isn't that... wasn't there some REALLY famous Christmas special that was sort of like that? I remember it being on every single year and referenced in everything... an outcast saving the day... hmmm... it's like there was this special where one of Santa's reindeer had some weird affliction that made everyone hate him, and at one point said affliction is extremely useful in saving the day. I swear there was some kinda reference to that in Nightmare Before Christmas... I just can't put my finger on it.
But seriously... it's like they took their version of Cloudy with a Chance of Meatballs and cross bred it with Prep and Landing. Even if this movie came out a year before or after and was in no direct competition with the Muppets I'd say ick. There's NO shortage of Christmas specials that are good. They just lost the know how to make GOOD ones.
