There is a LONG list of good properties that they just don't give enough love too. This is way up there. yet another one like Wall-E, Aristocats, Bambi, Robin Hood, Brave, Up, Hecules, Wreck-It-Ralph, Fox and the Hound, Rescuers, Big Hero 6... I guess it could be worse, they gave love to Tangled, they gave it a restroom.
I get it, they can't spend years creating a ride for a movie before it comes out and have the film fail and be stuck...and if they wait to see if it works, then they might miss the wave.
But Zootopia (apart from a 3 act that drags a bit) is one of the best they have done...and with an entire park that is already themed on animals, it should have been a no-brainer.
That and why can't they just do the smart thing and retheme the Tomorrowland Speedway to Sugar Rush?
