So most of the reviews I'm seeing come down to
a) it was brilliant or
b) it sucked because the inciting incident was a stupid mistake.
And the thing is, I think it can be brilliant and the inciting incident can still be a stupid mistake.
Because life is full of stupid mistakes. Life is full of carelessness, and us not asking the right questions at the right times. Life is messy, and we all think we're immortal. So we go about our days and we all have little moments of recklessness, because X has always turned out okay.

* If I were writing this show, I'd salvage older!Amy from that timeline just in time - and she would become Madame Kovarian. Breeding her past self and training her daughter to be the ultimate weapon against the Doctor, her betrayer? Who, at this point, has more reason to hate the Doctor and resent Amy than older!Amy? She has access to temporal engines to slow her aging, and she's learned to hack and build a sonic
