Yes, definitely watch Moffat's other episodes. There's a reason every Doctor Who fan punched the air simultaneously when it was announced he was taking over as showrunner.
Something for the old-school Doctor Who fans - this is the third time the Doctor's stolen his clothes from a hospital (Jon Pertwee and Paul McGann did the same), and every other costume change came from the TARDIS wardrobe!
Oh, and the TARDIS (exterior) is now the Peter Cushing movie version! You can tell by the St John's Ambulance sticker.
