Waters of Mars
Hmm. I didn't enjoy this nearly as much as I expected. There were strong Impossible Planet/42 vibes, making it feel more recycled than resonant, and the Doctor was largely passive.
I had some problems with the story. ( Snip for spoilersCollapse )katlinel
described this as mostly being a setup for what's coming next month, and I think that's right.
I think Granny Weatherwax would describe the Doctor's behaviour as cackling.
