Loved it, loved it, loved it. When I first saw the trailers for this movie I thought, "Oh no", another animated kiddie movie cashing in on the 3D craze. Not so, great story, great set design, great design of all the characters. Lots of little jokes, nothing forced, great for adults and kids. Laughed at a lot of parts and applauded at the end. The audience was a mix of adults and parents with kids. Definitely an A movie. I am surprised that there are not a lot of ads for this movie. Go see it, it is a gem.

Arthur Christmas - Rotten Tomatoes

The 3D, CG-animated family comedy Arthur Christmas, an Aardman production for Sony Pictures Animation, at last reveals the incredible, never-before seen answer to every child's question: 'So how does Santa deliver all those presents in one night?' The answer: Santa's exhilarating, ultra-high-tech operation hidden beneath the North Pole. But at the heart of the film is a story with the ingredients of a Christmas classic - a family in a state of comic dysfunction and an unlikely hero, Arthur, with an urgent mission that must be completed before Christmas morning dawns. -- (C) Sony Pictures
PS: I saw it in regular 2D and it was fine.
