I thought this was ... OK. I'm still finding the incidental music intrusive, and I'm not liking the amount of darkness, which just makes it difficult to see what's going on. I didn't like the darkness of the TARDIS interior at all - I preferred the Smith/Capaldi interiors, or even (gasp) the classic model.

I do like Graham - he's reminding me quite a bit of Ian - he thinks he should be in charge, but at the same time sees he's way out of his depth. (There was some line to that effect, I wonder if that's what you are thinking of).
