After 13 and a half seasons of randomly pottering around time and space, with the occasional dash of continuity, The Doctor finds himself back home and revealing unprecedented amounts about his his race and home planet.

This story has the rare accolade of being both set on Gallifrey and actually being good. It helps that a large chunk of the story is set in a frightening nightmare hallucination, so you never get a chance to get bored of the setting - which is home to assassination, lies and political games.

I like that The Time Lords are set up as generally being total bastards. It makes total sense of why The Doctor left his home planet. It was wonderful to see The Master back after all this time - and in a new incarnation. It only increases the grand sense of history this story has. It’s a very special 4 parter that fees like a reward for sticking with the show up to this point and a celebration of its 13 year history.
