After all that, I must say, this movie did not disappoint. I loved the first Shrek, with its mockery of Disney themes (exploding bird scene: absolute ownage). This movie easily equaled the first in both smarts and laughs. The animation was excellent, the voicing even better than the first, and the jokes kept cracking the audience up. Dreamworks' plays on words and themes were great, as well. "The kingdom of Far Far Away would like to ..."
The only thing I would have changed would have been a little less Donkey and more Puss in Boots.
When you go see the show, stay and watch the credits. There's a short extension hidden about three or four minutes in.
