Spoilers from A Good Man goes to War, don't read if you haven't seen it. River being Amy's daughter is kinda fucking stupid. I mean it was literally a joke on Doctor Who forums. I was really hoping for the Omega theory to work out. But he did immediately win me back over with "Lets Kill Hitler" as the next episode. Thats gonna be wicked.
I don't think so. I think it was a nice twist, and not every fan reads the forums. The title of the next episode is great, though.
