Look, if your kid is deep in the Dragon Ball universe, they're going to want to see this regardless of what I say. It's competent, the animation looks good, and fans seem to enjoy it (IMDb 7.1 isn't bad).
But let's be real: this is a movie where the entire plot is 'bad guys make androids, good guys punch androids, everyone powers up, good guys win.' The Metacritic 65 tells you what critics think—it's middling. There's minimal character growth, the story retreads the Red Ribbon Army from the original series, and it offers basically zero enrichment beyond 'fighting is cool and protecting your family matters.'
It's not unwatchable, but it's also not doing anything new or particularly interesting. If your kid isn't already a fan, there are way better entry points to anime. If they are a fan? Sure, they'll have fun watching Gohan and Piccolo beat people up for 90 minutes. Just don't expect any profound life lessons beyond 'train harder, punch better.'
