The Secret of Kells
The story and characters are a bit thin here, but that's more than made up for the music and the overall look of the movie [which are both just absolutely astounding]. The way it looks and animated actually reminds me of something like Samurai Jack, but far less restrained and with more money to work with. It moves along at a nice pace, although the ending comes a bit too fast [could have used another 10 or 15 minutes, I think], but that's a minor gripe and really the only one that I could even think of leveling at it. The fusion of Irish mythology and religious undertones is great and allows the animators to do some great imagery, especially in the forest scenes where the movie truly shines [and in the Viking attack towards the end, which is far darker than any other part of the movie]. And you can't go wrong with a lots of Celtic music. It's nothing deep, but it is really, really good.
