That last episode: Ringwraiths with lightsabres WHAT THE ACTUAL FUCK?!
Next episode's title also gave me a chuckle, although I do wonder where they'll go with it. Overall, the highlight of that half-series was Neil Gaiman's episode, and I do think that Moffat is pretty much out of (good) ideas.
If Terry Pratchett wrote an episode, it would probably be about the best thing ever. Period.
Let's not forget deus ex machina and Macguffins up the wazoo!
That said, for me the Neil Gaiman episode felt like something they found on fanfiction.net and turned it into an actual episode. I do agree that Moffat might just be out of ideas, I think, as far as Doctor Who is concerned, that he's at his best writing single episodes (or two parters), not so much at running the whole show.
I'll just second the Terry Pratchett episode, and I do regret that Stephen Fry never got around to writing his episode, should've been interesting.
