I just saw it a few hours ago. Overall, it's definitely one of the best animated films I have seen in a while. The animation was beautiful, the story was dark and suspenful, the characters were fun, etc. The 3D was done in a reasonable way and had me on the edge of my seat. I hope that when it's released on DVD/Blu-Ray they include the 3D version of the film, especially since I kept my 3D glasses. Even if they don't, I'm sure it will still look amazing.
