It's a jungle out there for Blu, Jewel and their three kids after they're hurtled from Rio de Janeiro to the wilds of the Amazon. As Blu tries to fit in, he goes beak-to-beak with the vengeful Nigel, and meets the most fearsome adversary of all: his father-in-law.

Like most sequels, Rio 2 takes its predecessor's basic template and tries to make it bigger -- which means it's even busier, more colorful, and ultimately more exhausting for viewers outside the youthful target demographic.
