I saw Rio last week. My brother took me to see it as a late birthday gift. here's what I gotta say about Rio. I should tell everyone that I am not a big fan on Blue Sky's cartoons. If you ask why, I will tell you why. Blue Sky has something in common with Dreamworks Animation. They have good ideas for animated films, but however they are not pullde off correctly. However, this one caught my attention and I manage to sit through the whole movie. While parts of the movie are humorous and having a very catchy soundtrack along with a great villian. Some of the music in this is rather good surprisingly, I really liked "pretty bird" and "Let me take you to Rio". Those two songs will be stuck in my head for a while. I would say the villan song makes it in my book on what makes the movie good. You gotta see how well animated this particular scenes is.
The humans in this movie look more 'cartoony' then in most animated films that are CG. They look like Doug Tennapel designed characters. Also the birds looked rather nice as well. They are heading towards a cartoony look as well. Did anyone here get a Saludos Amigos vibe from this? I know it takes place in Brazil but heck I got a vibe from that. I felt that certain parts of the movie had stuff in it that was forced. I won't say who said this line, but one character said "That's the Spitz!" orsomething on the lines of that. And the gangster stuff, uggh. I wish that they would stop shoving that stuff in nearly every animated film. It annoys me how they do that. It doesn't work for everything you know.
On the lines of voice acting, I wasn't aware that big shot stars were doing them. However these voices were good(minus the person who voiced the toucan). If they were to get actual voice acting for these characters I picture Rob Paulsen doing the Toucan, although I cant think of anyone else for the voicing the characters though. So you can say that I enjoyed Rio. If Blue Sky can make something like this, or on the lines of this I'd give them a chance. Although there was this one annoying kid who wouldn't shut up throughout the whole movie, he kept yelling "BIRD! BIRD! BIRD!". Where are the angry birds when you need them?
