I'm so sick of the "save the universe every episode!" style. I agree that he's better writing one off episodes, or writing with a partner who can temper his wilder ideas (ie Mark Gatiss in Sherlock).

Yes! Moffat, like the Doctor, sometimes needs somebody to stop him. When he doesn't get that, he has a tendency to throw too many things into the show not because they improve the story but just because it seemed like a cool concept. He sets up situations where the stakes seem super high every time, but then he also shies away from real consequences like characters staying dead.

When he's at his best Moffat can produce some genuinely fantastic work, but being showrunner of Doctor Who has generally not inspired his best.
