Don't look away... don't turn your back... and don't blink!

I thought this was another very fine episode. Very scary monsters.

Just a quick comment, so I'll try not to say anything that needs a cut tag. I like the idea of episodes where the Doctor only makes brief appearances, and I though this one worked a lot better than last year's. The last one was sort of a joke episode, but this one was quite serious, and I thought it worked really well.

Oh and the ending... quite profound.
