Moffatt was great for short burts. Often the best episode of the season, or a great little mini-arc across 2-3 episodes. His problems always manifest when he is writing whole seasons. He quickly goes off the rails and backs himself into stupid corners trying to one-up the episode before.

That was the first episode of Doctor Who I iver watched, and nothing has really been able to achieve that high. Don't Blink is probably my second choice.
