I just watched Rio and it was... kind of disappointing, actually. I have a soft spot for good animated movies, even if they're usually directed at kids, but this one just didn't quite do it for me. The plot was all right and a decent cute-kids-movie cliche, which isn't such a bad thing. I thought the music was kind of lacking. Maybe I'm just a snob when it comes to musical animated films because I grew up watching so many Disney classics, but I thought the music was just trying a little to hard to seem modern and different. I'm sure it probably worked for some people and some of the songs were all right I guess, but for the most part, I wasn't impressed.
Overall, it was an all right movie, but not one of the animated films that will make it on my Possible Buy list.
