Great Christmas fun, even if a little watered down for Aardman. I don't think Sony Animations really nails the Aardman look, but it's close enough I guess. Grandsanta provided a lot of laughs, but the rest of the time I was struggling to stay engaged.
Ah yes, M Night managed to knock off another one that is not only stupid but also dull. It's a shame that even a full cast of great actors couldn't manage to ward of the curse of Shyamalan. Even if you want to do a big reveal don't save all of the points that move the plot for the last 15 minutes.
