Look, if your kid is in peak Pokémon obsession mode, this will keep them occupied for 70 minutes and they'll probably enjoy it just fine. It's safe, it's predictable, and it hits all the expected beats.
But let's be real: this is a thoroughly mediocre entry in an increasingly tired franchise formula. The 5.5 IMDb rating and 58% audience score tell the story—even fans were like 'meh, it was fine I guess.' The 'discover your inner power' message has been done better in basically every other Pokémon movie, and there's nothing here that'll stick with kids beyond the runtime.
It's available free on streaming, so if you need something to keep the Pokémon fan happy on a rainy afternoon, sure. But don't expect anyone to be quoting this one at dinner or asking to rewatch it. It's the cinematic equivalent of eating plain rice cakes—it'll do the job, but nobody's excited about it.
