Tell me if I'm totally off base here, but I don't know a single family whose kids were happy they saw It's Tough to be a Bug. I have friends (and siblings!) that still talk about how terrifying they found the show. I understand why adults might bemoan losing a truly scary attraction, but It's Tough to be a Bug was a one and done for every family I've heard talk about it.
Now, I think Zootopia is a bad movie and I couldn't care less about this new movie. But, hey, if it doesn't terrify kids it seems it's at least a lateral move for the park's attraction mix.
