Doctor Who: The Gathering

Although it also gets four stars, I'd say this is slightly better than its prequel/sequel “The Reaping”, which is set later from the Doctor's perspective, but earlier from everybody else's. As such, it ties up some hanging plot threads from the end of the story, as well as explaining what it had led up to it, and also acting as a prequel to the 7th Doctor story “The Harvest”, which it helps to set up.

But the real point of the story is the examination of Tegan's life since she left the Doctor, and it's here that the play nudges ahead of “The Reaping”. The two work better when taken together, with complementary themes as well as the more direct plot links, but even on its own, this does respectably.
