M'eh. I didn't think it was that bad, I just don't like amy and so resented her stealing rory's thunder, I thought her talking to river like a mother to a daughter was ill-placed (such interaction should have been played for laughs in previous episodes and not been during a tender moment).
That book must have been very odd to anyone else who read it.
It's a 45 minute programme. I'm pretty sure 10am the next morning is plenty of time for people to have got home from any post match fun and still watch it.
I don't like the "Angels" much and the episode was a just a way of getting rid of Pond and Rory. It's a pity that we won't see Mark Williams (Rory's dad) as he's an Albion convert. The River character would be better if she stayed mysterious and only popped up briefly now and then.
I thought it was pretty good, and I'm glad the Angels where more like the originals as opposed to that dreadful episode where Moffat really over-egged it. As a general point I've also really appreciated the fact that this series there hasn't been some pompous, overblown story arc running through all the episodes ending up with the Doctor as the centre of the universe having to do preposterous things to bring a series to a close. This has been more like the originals with the Doctor as just a relatively insignificant speck and not some galactic Superman.
