I liked WolfWalkers, it was really different from anything I've ever seen, a very heartfelt story with unique characters and mechanics, great music and incredible drawings.
My only problem, If I must find one, is the final twenty-or-so minutes, which were a little too dramatic, at least for me.. And I probably would have opted for a slightly different ending, but this it's not a critique, it's just personal taste.
See this if you want to immerse yourself in a different but good experience with great, natural sceneries.
