The first time I watched this, I loved it. However, on a recent rewatch, I didn't love it quite as much (don't get me wrong, it's still great, but more like 4.5/5 than 5/5). At first I thought that this may be due to already knowing the plot, but I watched it multiple times close to release and loved it each time then. As such, I think this is due to the context of when it was released (and hence when I first watched it): coming off the back of the Chibnal era and directly following The Star Beast, a story that I find dissapointing at best, this was incredible, and, in my opinion, probably the best Doctor Who aired in a while. Now that Ncuti's first season has concluded and I've also been rewatching a lot of older episodes, this story doesn't stand out quite as much. However, I do still think that it is excellent: with the exception of the slightly random opening scene, it is tight and well-paced, fitting togethger really nicely to create an exciting and intriguing narrative. The villains are a really cool concept. The set and CGI (which aren't really things you can talk seperately about for this episode) look excellent (although I didn't find it quite as realistic as I did the first few times I watched it). Overall, a really solid story and the probably the best in a while at the time of its release.
