4.5 Doesn't fly so high RJNeb2 | 16/05/2013 | See all RJNeb2's reviews (644) It may be nicely animated, full of bright sassy colours. It might have some fun characters and a game if overly qualified voice cast. It zips along at a quick pace and it has a killer song score from the legendary Sergio Mendes. But there does not appear to be anything particularly distinguished about Rio other than it being innocuous and a reasonably amusing way to pass an hour and a half. And try as they might (despite the best efforts of Jemaine Clement), it is almost impossible to turn a cockatoo into a mean villain.
