It's no Midnight.

The Well works as your run-of-the-mill sci-fi horror story, except it's a secret sequel to Midnight, with half the characterization, half the writing quality, and somehow, despite the fact that Midnight is a bottle episode that is basically 100% talking, half the story.
That's the trouble with making a sequel to one of the greats, you invite comparison, and in this case, in my opinion, I don't think it's a favourable one.

The story feels like it's building to something big and emotional, a big crechendo, and then The Doctor shouts something to the effect of "I got it!" and suddenly the mood is ruined as it tries, for some reason to have a big, high-energy, save-the-day, run-for-your-life moment, only to kill that momentum immediately afterwards, which in my opinion, just doesn't work at all. It doesn't feel like hope just before the world comes crashing down, it just feels like it wants to be that, and tries to be that in the most brash, in-your-face, ott way possible.

A problem I have had with these two series is that the individual episodes feel small, short, like it's missing a little something that nu-who had for each episode to feel as grand as they could. I personally write it down to their reliance on sets and - seemingly - downright refusal to do location shoots, but perhaps there is something in the writing which feels less substantial than some series, I don't know, I'm still chewing on that. But, whatever it is, I feel it here again, it feels like we've just gotten to the middle point and then it's time to wrap everything up in a neat bow. Maybe stories are too verbose, this episode is certainly an offender of that. Just endless talking of being sad and missing your family in a way that is meant to be impactful, but never manages to feel it for me.

All-in-all it's a decent episode of television, no more than that, one that is perhaps a little confused as to which tone it wants to convey at times and spends too much time yapping without telling, or telling without showing, but really, it's biggest sin is being unremarkable.
