Well, I've got to say that this movie has one of the weakest plots I've seen in an CGI animated film. While I know I'm suppose to suspend my disbelief with these kind of films, but some scenes really had me scratching my head, especially after the courtroom scene. So all of the world's bees are in/around Manhattan? Dead flowers can be pollenated? Bees can fly as fast as a jet airliner? In fact the whole climax with the jet seemed completely random and artificial as a conflict. It wouldn't have bothered me if the plot was treated as a complete farce, but since it seems to want the viewer to take it seriously in spots, it didn't really gel with me. I couldn't help but laugh at how evil those beekeepers were.
Jerry Sienfeld and Renee Zellwinger's characters pretty much carry the entire film with their humor and charm. Plenty of witty jibes kept me from paying too much attention at most of the plot's flaws. While still a far cry from Pixar, the CGI rendering looks like it's improving, especially for the human characters.
So I found it a rather uneven film that sort of lost momentum about 2/3 of the way in despite maintaining a good amount of comedy overall.
