I thought it was a nice breather episode where the Doctor wouldn't have to make yet another moral choice on whether or not it's okay to kill the big bad of the week. That said, Matt Smith is really beginning to annoy the heck out of me. Not even Tennant or Eccleston displayed a complete inability to sit still for an hour. They (like all the doctors before them) were actually able to sit down and shut up for a while. Is it too much to ask for a thoughtful introspective Doctor who knows how to conduct himself in social situations? Even Tennant, for all his wangsting, was still able to relax. Why can't they let Matt Smith relax? We don't need an ADHDoctor to keep the show fun and interesting.
