My only complaint was the gratuatious pandering to the lonely male demographic, something I would expect from tomb raider or star wars, but had thought doctor who was above. I mean seriously, yes you have a pretty girl, that is no excuse to put her in a police uniform with a stupidly short skirt she constantly has to pull down and top that off by giving her a job that no matter how much of a sad lonely sap you are, she might still kiss you.
What makes it even worse is when you compare it to Moffat's past show, Coupling, (where I'm pretty sure he imbued the characters with his own fetishes and turn ons). Women in uniform - tick. Stockings - tick. We're one lesbian kiss away from it looking suspicially like a creepy old man forcing a gorgeous young girl to play out all his fantasys for him via the medium of a massive hit tv show.
Everything else though, was brilliant. Stunning. Perfect.
