A perfectly solid story!

A 'base under siege' story is very much classic Doctor Who, and it's a story concept that always feels like it fits perfectly wherever it is it ends up being, here being no exception. Our core cast are nice, kept to just three extra characters which lets everyone have time to get uniquely characterised.

The threat itself is pretty solid, and I really like the ties to the mythology of the peoples, and the mechanics of how they function. Plus the imagery that's used here is really great, 'psychic energy panthers' is just a really really fun image.

Also I loved the romance we get in this episode, the character dynamic is sweet, always love a bit of queer rep, and the lampshading classic who companion's exits is also funny.

That all said, I think this is the 11/Valarie story not to blow me away. It's good don't get me wrong, but it's definitely 'solid' not 'stunning'. When that's the worst thing I can say about a story though, especially looking at the rest of the range... what's the opposite of damning with faint praise?
