This episode is a step up from Space Babies, but I still think it's far from peak Doctor Who. It has a decent core concept which, unlike the last episode, I feel is well explored. However, it still feels a little bit messy. Still, it is good fun and enjoyable. The bit at the end is... interesting. It feels a little bit out of place and disconnected, but is entertaining in its own way.

One very nitpicky thing that I noticed and feeled compelled to point out is that, when a character way playing a violin, it was very obvious to me, as someone who plays violin, that it was not being played properly, and this made me struggle to enjoy this scene. That's possibly just me, though.
