Pixar's Up puts a cap on the Many Movies of May series (Wolverine = 1st, Star Trek = 2nd, Terminator: Salvation = 3rd). There's a sort of geek prerogative to nitpick these sci-fi/action/adventure comic book movies. It's why "the Good, the Bad, and the Ugly" isn't "the Good, the Pretty Good, and the Bad". Movies in the genre of Up, however, don't lend themselves particularly well to the GBU format. Still:

The Good:

• Characters, story, music, visuals - it all sparkles.
• Refrained from fart and poopy jokes and pop culture zingers that are the usual bread-and-butter of (non-Pixar) CGI films these days. I'm all for fart/poopy/zingers, but it's nice to get an animated break once in a while.
• The talking dogs were terrific. That sorta thing takes a light touch, and these guys were handled just right.
• The "Partly Cloudy" animated short that plays before the feature was one of Pixar's best.

• The details of Russell's family life were too hazy and superfluous.

• Not a fan of the goofy easter eggs Pixar puts in these movies. The half of my brain searching for the Toy Story pizza delivery truck (which it never found) prevented me from being completely absorbed by the story.
