I have to agree with all of the critics and fans, this is a great animated film. And I didn't even see it in 3D. I didn't need to. I could tell exactly which scenes were framed to take advantage of 3D. But I'm a little over that, myself.
Not much to say, other than good story, good characters, good pacing, fun times. One question: why do ancient vikings speak with a Scottish accent? I'm sure there's an explanation somewhere.
