Yeah, Rio is a kids’ movie, and in a way it should be cut some slack for that very reason. Judged solely on that criterion, it’s colorful and fast-paced, and a perfectly acceptable distraction to set your kid in front of. Beyond that? Think of it as the prettiest Saturday morning cartoon you’ve ever laid eyes on. This by itself isn’t necessarily a bad thing. Even the generic, unsurprising plotting shouldn’t be an issue with this kind of movie, as long as the material is there to carry it. Unfortunately, what we get is a Three Stooges marathon worth of slapstick for 96 minutes. It doesn’t help that there’s little to cut all the busyness with, since the plot — about a domesticated macaw named Blu (voiced by Jesse Eisenberg) who never learned how to fly on the run from bird smugglers in Brazil — literally does exactly what you expect at every turn. The voice acting is OK, mostly dragged by Eisenberg’s continued insistence on sticking with the Micheal Cera path to fame and fortune and becoming a dull parody of himself. The pity in all of this, however, is that there is some handsome animation (and some striking 3-D effects), and even some nice production design here and there. But what good is any of that when it’s plastered on top of a pretty lackluster movie?
