I already know this is a movie I'll be rewatching a few times, not just because it's a great watch, but because of the many great Easter eggs, many of which I'm sure I missed. Lots of jokes for the grown ups to enjoy.
Great story, beautiful animation, a real Disney feel to the whole thing. Lots of laughs and lots of feels. The setting is a little absurd but bring your suspension of disbelief and don't ask too many questions about how all these animals can live in harmony in a seemingly evolved state in a world devoid of humans.
