Mr Moffat's dream of making each episode it's own little film has so far been working out. Today looks suspiciously like Cowboys and Aliens, but here's the BBC's blurb: "The Doctor gets a Stetson (and a gun!), and finds himself the reluctant sheriff of a Western town under siege by a relentless cyborg." Stetsons are cool, I guess! I am a little wary of this episode, but as the middle of only five precious outings for the Doctor, I'm willing to embrace it wholeheartedly!
