4.5 stars out of 5 -- "[RIO] flies high on comedy, heart and great music....It's perfect family fodder with a sterling voice cast..."
Box Office "Seldom has a film been so endearingly besotted by the possibilities of flying....Watching RIO means living happily in the moment."
Wall Street Journal "It captures the lush beauty, musical rhythms and energy of Rio de Janeiro with a deft blend of vibrant visuals and spunky charm."
USA Today "The opening, set in a Brazilian rainforest, is a floor-show extravaganza: All manner of winged creatures in unreal colors -- the flaming orange of Mercurochrome, the outer-space blue of artificially colored popsicles -- dip and sweep among the trees."
Box Office "[T]his animated feature effort is a significant step forward...in the richness of its cast, the exuberance of its music and the vibrance of its palette."
New York Times 3 stars out of 5 -- "As colourful as its heroes' lovely plumage and with some pleasing aerial set-pieces..."
Total Film "[With] sunny panache and colourful detail....The macaws are a pleasant comedy twosome..."
Sight and Sound "Though the colors are primary color fabulous, the real trick is in the character design and movement, unerringly naturalistic in that splashy cartoon way..."
