To keep it simple, good for kids/family but for teens and adults it's not worth the time.
Story
Really promising in the beginning, because we get what we came for, the boy trained by the beast, but later we will get other "emotional" plots that don't have enough time to feel relevant and can become boring and predictable
Characters
Simple but likeable, they have some personal struggles to make them feel more alive but make illogical decisions sometimes
Antagonist
No motivation, no logic, no buildup
Visuals and music
Very beautiful, probably why the movie is even relevant
Is it bad? no, but for a 2h movie is just not worth it
