It’s a fun movie, especially for fans, but there were quite a few things that bothered me.
Some continuity errors, the pacing, the soundtrack choices, and even the animation itself.

The movie starts off strong—great use of CGI and some amazing visual direction—but as it goes on, you start to notice the quality dropping, with less fluid animation and a lot of static panels.

Motivations/backstory of Demons are so simplistic you wonder who the fk wrote this and thought it was a good idea.

Fights as usual were top notch
