It's A Thing: Robot of Sherwood

Moffat-Era Tropes: Having Mark Gatiss write a story full of Gatiss' own set of tropes. An episode where the Doctor and companion walk into some sort of mythical scenario (e.g. pirates) and the companion promptly starts playing up to it while the Doctor sulks about being sceptical. Banter. People gabbling things out far too fast. Scottish jokes. Patrick Troughton references. Robots fixing a spaceship with whatever they have to hand.

A Thing in a Thing: A robot in Sherwood. Actually several robots and a cyborg.

The Doctor is A: Bony rascal.

The Master Is A: ...way this episode. Probably watching the other channel.

Clara Lies About: Her story to the Sheriff of Nottingham, as she tells him later.

More realistic than this.

Reasons Clara Should Drop Danny Like A Hot Potato: Because she's having a little fling on the side with Robin Hood.

Child Count: None, but there's a dwarf to make up for it.

The Thick of It: The Doctor is in a permanent strop, but then again, confronted with the scenario he's in, any sane person would be.

It's Actually About: ...no, seriously, what is it about? Robin Hood et al. Shouldn't exist in the form they do here, for countless reasons (just look up “Robin Hood” on Wikipedia and count the anachronisms in this story), and yet there's no indication that this is the Land of Fiction, or a case of people being mentally conditioned as in “The Next Doctor”, or any of the rationales the Doctor suggests for this ridiculous setup (Miniscope, theme park, etc.), or any connection with the Master and her virtual world either. There's no explanation for the warm climate or the general unreality of the scenario. There's an exchange at the end about people needing their heroes to be larger than life, but then again, since the heroes in this story are larger than life, there's no Firefly-style message about the reality of heroism versus the fiction, either. So all I can say is, it's about 46 minutes long.
