This movie was amazing! I'm not surprised people are hating on it though. Honestly, if a child likes it, it's probably a good movie, it's targeted towards kids, like me.
The haters are adults who expected a cinematic masterpiece like Into the Spiderverse and were anticipating something that wouldn't come with a simple kids' movie for KIDS.
It didn't have to be deep, it had amazing music, it had a pretty good narcissistic villain, and had many diverse characters. The animation was beautiful and I loved the choice of the voice acting.
It was funny and I loved the idea the movie had, I do recommend watching it!
