Absolutely zany, but like the best Aardman films, the zaniness manages to be tasteful. Some of the funniest gags in a Christmas movie for sure. And honestly a pretty touching moment at the end. It's a bit of an information overload at times with hyper visuals and quick-firing dialogue (a similar feeling I had watching The Mitchells vs. The Machines... am I just getting old?) but overall very sweet, very funny, and very much going to be a Christmas staple from here on out.
