So this was the second part of the Silurians story - and we'd thought part 1 was rather weak. Part 2 was better tho, so that's good :) More Amy - I liked that she escapes herself, rather than being rescued, and the pickpocketing was something that had been set up before (in the Daleks in WW2 episode). The scientist Silurian was nicely ambiguous - willing to dissect the "specimens" he had, but not the children, and not willing to just start a genocidal war or execute people out of hand. And the guy he had dissected wasn't harmed permanently. And who wouldn't go a little nuts after 300 years on their own?
And I liked that we avoided the total tragedy ending for the Silurians, even though it was on the cards after Ambrose killed Aleya (sp?). Going back to sleep again for another 1000 years, with two humans with them (I'm assuming they'll cure the old guy so he won't mutate before they all back into suspended animation), so hopefully the world will be "ready" for them by then was in retrospect the "obvious" other solution but only possible because not all the Silurians were xenophobic. Kinda liked that the total nutters were both of the same family - so not necessarily all the Silurians, or even half, but more the sort of people who end up doing well in their military or a family "issue".
Aleya's death was fairly well done too, I thought - Ambrose had been set up as the sort of person to take things too far then regret it, I thought. And we'd already seen that weapons were her first thought, and that she was protective of her family. And with Aleya taunting her because she wanted to die and start a war, what chance did Ambrose have to stop & think first. Poor Rory trying to keep control of the situation though - without the "presence" of the Doctor (I mean his charisma & his seeming ability to make everyone listen in the end), it wasn't going to be easy and Rory didn't have that sort of personality anyway.
Poor Rory dying too :( Again trying to do the Right Thing - and saving the Doctor. Then being forgotten as well (although not by the Doctor), poor Amy even though she doesn't know why anymore. I guess the "look there's us" from the start of the first part was just to set up the "look there's me" at the end. I'm guessing Rory won't stay dead though - the ring is still there in the Tardis & the Doctor still knows, so I don't think we're done with that plotline. Putting right the cracks reverses things like that, maybe?
I noticed "trust" came up again - Rory trying to get people to do the right thing by telling them to stick to the Doctor's plan because he trusted the Doctor (trusted the Doctor "with his life", in fact ...). The Doctor trying to get Amy to remember Rory, telling her to trust him to help.
Oh, and just after posting this I re-read magid's comment on my last DW entry as I'm replying to it now & remembered the Great Big Plothole as far as I was concerned - why the rush to escape at the end?? The poisonous-to-Silurian gas doesn't seem to affect the humans (or the Doctor) because the one who comes to assassinate the Doctor is already dying and the others aren't affected. So why rush to get out? The Tardis is a time machine, it can take them from tomorrow/two hours time/whatever to the right moment on the surface. It just seemed there for dramatic tension :/
