Very earnest.

I could really feel that this was a passion project, it exudes such a cute and pure whimsy that is hard to resist. The animators obviously had a ton of fun as well, crazy face shapes, different styles entirely and the big action scenes felt very good. It would have been very easy for this movie to fall into safe corporate "quirky" but it came across as genuinely what the creators liked and found funny.

The How to Train Your Dragon reference was a cute surprise, but I guess it makes sense for a movie that came out more than 15 years ago (damn, I'm old).

The pacing is my biggest problem with it, as it feels like it wants to show off so much while never having time to dive any deeper. It often feels like we're rushing through from one sequence to the next with very little breathing room. As others have pointed out, the ( 2? ) villain's motivations are quite underdeveloped. It seems like they had a villain ready but realized they made her impossible to reason with, so made a second one. Which is also isn't that evil after all, since she's quite easily convinced to stop being bad? It felt a bit messy.

Despite that, the message of friendship and remembering lands quite well and ties this up into being a cute, positive movie.

I hated the baby demon, please never again.
