If your kid is a Whoniverse completist, this is mandatory viewing. It’s a gritty, tech-heavy expansion of the UNIT lore that treats its audience like they can handle a complex plot.

However, the audience scores tell the real story: it’s a bit of a slog for casual viewers. Without the Doctor’s chaotic energy to balance things out, it can feel like a very long episode of a standard military drama that just happens to have lizard people in it. It's solid, but don't expect it to be the next big family obsession.
