I guess we've just got a difference of opinion - I happened to think Cloudy with a Chance of Meatballs was one of the most charming movies to come out that year. g to be what you expect, and I've never found any magic in the expected. As for Aardman/Sony's previous effort, Flushed Away, I did think it was minor work for them, but since when does everything have to be a homerun? I think if you enjoy it, it's good enough. Meanwhile, I don't think you need worry about Arthur Christmas taking any tickets away from The Muppets. One of the two has received heavy advertising and promotion, one of them has not.
I don't want to list all the reasons I hate Cloudy, but I'm VERY close to the book. it's one of my all time favorites. But they explain something unexplained that didn't need explanation. And in the most banal way possible. Plus, I like my scientists MAD... I LOVE Igor, Megamind, and Despicable Me... Mad Scientists are one of my favorite character tropes. If I studied Science as a career, I'd be the most real life equivalent of a Mad scientist possible. But well meaning scientists that never felt like they had their fathers approval? No thanks.
On the other hand, I love what they did with the Mr. Men show... but they didn't change things other than the fact there were no wizards, no morals to tales, and a couple characters' genders and they lived all together in a single town. But that's something else completely.
As for Flushed Away, that was one of the 3 movies planned under a Dreamworks/Aardman partnership. Of course, only 2 were even made (the other being the stop motion full length Wallace and Grommit: Curse of the WereRabbit)... a third one was to be written by John Cleese... Dreamworks is still going to make that film, but with massive changes to the script. Flushed Away was great for those who love British humor... especially the British portrayal of the French (they're nastier to the French than we'll ever be) and Americans (annoying tourist couple...heheheh). Plus, they managed to translate their classic Banana mouth look to CGI. Arthur just looks like everything else.
I know I shouldn't worry, but if history has taught me anything it's that people like to watch Family Christmas movies that come out during Christmas. That's why the first Chipmunks movie was a surprise hit... that song. Also Elf (which I don't get at all)... but in recent years, that's taken a turn. That hideous mo-cap Christmas Carol I mentioned before didn't perform that well despite HEAVY promotion (Jim Carrey was better in the 90's anyway)... and there was something else that didn't do too well. Hopefully the Muppets will stand out, and those seeking Christmas cheer will just watch Rudolph and Frosty.
