One of the most interesting things about Walt Disney Feature Animation is the way it has evolved over the course of its history from Snow White And The Seven Dwarfs to today. There are such distinct eras in its development, such major shifts in creative energy, such giant peaks and valleys, that even the worst moments in its history are worth study for animation fans. I wish Disney would embrace their entire history and not just their hits, because there is so much to learn from films like Song Of The South or The Black Cauldron. Right now, though, they have hit a stride that is admirable, and Zootopia is another triumph for the current version of the studio following films like Tangled, Wreck-It Ralph, Frozen, and Big Hero 6.
First and foremost, Zootopia is a reminder of just how beautiful animated films can be. Holy cow, this thing is almost hallucinatory. Set in a world where both predator and prey have learned to live together, Zootopia itself is a city divided into impossible sectors, with Tundra Town right next to Sahara Square, both of them adjoining a rain forest area and an entire miniature city just for creatures the size of mice. It's like the most insane safari park in the world, but with walking talking animals, one of which is new to the city, pursuing her lifelong dream of being the first rabbit cop.
