This had a very similar flavour to A Good Man Goes to War and Let's Kill Hitler, which as a trilogy have too many ideas. Some of the ideas are great, but they aren’t given the space to reach their potential. Moffat seems more interested in being clever than creating a satisfying whole.

Not to do it down too much, there’s a great TARDIS crew here and a good extended cast. Moffat has done a great job of making you care about these characters but there are aspects of his writing which come across a little tired all these years later. The cringe flirting and the mild sexism is just tiresome.

I liked seeing the lengths River will go to protect her husband. And how powerful Amy was in this episode. I was less keen on the Silence who were used to random effect and Madame Kovarian, who we never really get beneath the surface of.

I don’t think Moffat ever goes this “complex” again. Ideas that would be better contained within a single story tend to stay that way from here on out.
