Recently rewatched Logopolis and was struck by how Steven Moffat-y it was:
* paying off a vague arc in the season finale
* hints about future knowledge that don't quite make sense (like, what did the Watcher tell the Doctor to send him to Logopolis?)
* dropping said hints as soon as the story is over
* the first half of the story is spent preventing the Doctor from getting to the actual plot
* tying the regeneration into some kind of universe-level threat (to be fair, this is both Moffat and Davies)
Most importantly, I think: is Logopolis the first Doctor Who story to be completely about the show itself? By this, I mean, the Doctor usually stumbles into other peoples' stories: the Tribe of Gum trying to make fire, the Thals trying to survive in the woods, and so on.* But there's no story to Logopolis independent of the fight between the Doctor and the Master and the deepening of the mythology about the TARDISes. He doesn't interrupt someone else's story; from the beginning it's about the Doctor trying to better protect himself from the Master, and there would be no story if the Doctor didn't allow the Master to infiltrate Logopolis. It strikes me as very Moffat move: compare tales like "A Good Man Goes to War" or "The Big Bang" or "The Wedding of River Song."
* I guess Inside the Spaceship is an early exception to this.
