Maybe three stars is a bit generous. I feel about this episode in a way that defies stars, really. I think I enjoyed it, but it was definitely mediocre. But it's mediocre in a different way than The Robot Revolution. It's mediocre in a way that compels a reaction, which I think makes it better.

About halfway through I was thinking, "This is pretty much just a ripoff of Midnight" and then of course it turns out to be a sequel. Perhaps one might consider The Well to be to Midnight what Attack of the Cybermen was to Tomb and Tenth Planet. I don't know if I'd personally endorse that analogy, but it's food for thought.

There was definitely a lot of Idiot Ball tomfoolery. People were constantly being stupid and were only smart when necessary. I'll admit, this annoyed me a bit. Conversely, I was actually laughing during the scene where half the cast got killed. The lighting, camerawork, and soundtrack all came together to create one of the most unintentionally funny scenes in all of Doctor Who. Great job! Also, the ending lasted way too long. I was mortified to see seven more minutes remaining after the story had completely run dry.

It was great to see a traditional science fiction setting again, but there really isn't anything in this episode that we haven't seen before. It's literally just an inferior ripoff of the episode it's picking up from. Also, while I personally am not affected by this, I must wonder what it must be like for new viewers on Disney Plus, who haven't seen Midnight. This episode doesn't give sufficient context. Even I was a little confused, since I only watched Midnight once, several months ago. But I know others have complained about this enough already. I personally doubt there are that many new viewers tuning in at this point, anyway. I haven't been paying attention to leaks or Dr. Who-related news, so I don't know what's currently in store for the show's future. But if the choice were mine, I wouldn't renew this for another series.
