Do you remember what The Doctor told Amy when she was seven years old? And, more to the point, do you remember what we told you in our review for ‘Flesh And Stone’? Just two little words: continuity errors.

Say it quietly, but there’s not a lot in post-2005 Who that feels like old-Who. Don’t you just want just one old-fashioned, creepy, gloopy, slimy horror, with smoke-filled corridors and actors in green rubber suits?

‘Amy’s Choice’, at first glance, is one of those episodes where the plot is running on the spot. But it’s certainly not running on empty.

Stop whatever you’re doing right now, and listen. Can you hear it? The lull before the oncoming storm. Something is about to happen.

Frankly, anyone can create an all-powerful monster or villain, one who can’t be killed but kills indiscriminately, one who is big enough and bad enough to be Big Bad enough to be a threat to the entire universe.

So, just four weeks in, and already it feels like there simply isn’t enough time to stuff in all the dangling storylines that have been hinted at.

Now, this is more like it. After a circling of non-plots for Matt Smith’s opening stories, we hit the ground running with a genuinely scary, gorgeous looking, very grown up, and fiendishly clever Doctor Who adventure.
