It’s OK, this is safely spoiler-free. It’s just my initial reaction to tonight’s second episode.
Wow. Excellent mixture of scares, laughs and with an extra-large Moffat-sized dose of what the photon just happened?
There was a nicely unexpected bit that looks likely to be a set-up for the Big Bad things likely to be happening in the build-up to the mid-series cliffhanger. Very nice indeed.
And there were several unanswered questions, which may or may not be cleared up later.
A more coherent post may follow when I’ve had a chance to watch both parts of the story again, and after a decent interval has passed to allow for anyone crazy enough not to be watching it as soon as it’s on.
