Spoiler sport...

Why did nobody tell me that Saturday evening's Doctor Who was the first part of a two parter? I like to know these things in advance. Now I have another four and a bit days to wait for the conclusion. I wasn't mentally prepared for this. And add to that that this is the best episode of the series so far, which only serves to increase the annoyance. Aaaaargh.

Full review to follow once I've seen the conclusion.
