I haven't seen this movie in 3D, but that doesn't mean I haven't seen this movie. I'm not sure, but I don't THINK this is one of those movies where you haven't seen it unless you've seen it in 3D! I mean, be with the break giving!
So, Finding Nemo is a long movie. At times it's like, "Find this kid already!" But at times, oh, there is laughter! Then there's the classic 1/2 hour Pixar climax, (The Nightmare Before Christmas's climax lasted about 3 seconds, and should have taken notes, except it came out WAY before Pixar films.) During these long, agonizingly suspenseful climaxes I have to remind myself, "It'll all be okay. It's Pixar." Then I can get through them without screaming, or needing to leave due to anxiety.
However the award for Boonie's Best Pixar Film goes to Toy Story II. (NO, not III. I know, you can't believe it.)
