3Below is solid middle-grade sci-fi that does exactly what it sets out to do: entertain kids with alien hijinks while sneaking in themes about belonging and empathy. It's the second installment in del Toro's Tales of Arcadia trilogy, and while it doesn't quite reach the heights of Trollhunters, it's far from filler.
The premise—two alien royals hiding in plain sight at a California high school—gives you classic fish-out-of-water comedy with enough heart to keep it from being purely silly. The animation quality is strong, the voice acting is good, and the storylines move at a decent clip.
The main limitation: without much detailed information available, it's harder to assess specific episodes or arcs, but the IMDb 7.6 and age 7+ rating suggest it's reliably family-friendly without being boring. If your kid is into animated sci-fi adventure and you're tired of low-effort Netflix content, this is a safe bet that won't make you want to leave the room.
