I am the Kat that Walks By Itself

Also, re The Lie of the Land, I totally agree; Extremis was a brilliant set-up for a three-parter, but was badly let down by what followed. I think most of us could have come up with better plotlines. We didn't even get Erica back, when she was the saving grace of the Pyramid episode!

After seeing The Eaters of Light, I did wonder whether there was some significance in the repetition of the motif of a young woman insisting that the threat to Earth was her responsibility, she had to fix it, and the Doctor must be forcibly restrained from trying to do it himself. And TEoL also repeated the motif of the soldier(s) who'd previously run away but now faced death without flinching. But, though I did enjoy The Empress of Mars, I'd take The Eaters of Light over any of them. It was Good Stuff.
