I'm sorry, but I can not tolerate reset buttons. It's one of the laziest tropes around. Family Guy sums it up best when they refer to reset buttons as a "middle finger to the audience." And thta's exactly what this felt like. Unlike prvious Doctor Who reset like Last of the Time Lords, The Big Bang and The Wedding of River Song where the episode's main cast at least remembers everything after the reset, it would seem this is a full reset where no one remembers. Well, okay, it's kind of implied the Doctor is still aware of everything, but that's it. Clara forgot everything she learned in the TARDIS library including the Doctor's name (or I guess even that the Doctor has a name he keeps secret) and the salvaging brothers are still playing their cruel prank of making the young guy believe he's an android, though apparentally the middle brother is starting to stand up to the older one about picking on the android/little brother.
The tour of the TARDIS isn't all that impressive. For the most part everyone is just walking around the same corridor. Sure, we get glimpses of a telescope and the often spoken of swimming pool as well as seeing the library and engine room, but I don't know. I get they didn't want to go all fanwanky, but couldn't they have at least thrown in something more than Sylvester McCoy's umbrella and audio clips of Christopher Eccleston and Karen Gillan?
I don't know. I want to like this episode, but it just feels so pointless. It's not very often I call an episode of Doctor Who disappointing, and to be fair there are episodes worse than this. But damn, it really wasn't that good.
