Man, I thought people got all shitty about Star Trek and Star Wars.
Alright so I have this on Zune, so I watched it a few times. A few things:
Line of sight: There is no specific scene where the 'rule' is violated horrendously as people are whining about, and on the few instances there are...
Solving Line of Sight: As there are a fuck load of Angels now, if they get stuck, their pals can just come up behind them and cover their eyes until the one that is stuck is safely away and rinse and repeat. The reason that trick worked in
Blink was because there were only four Angels (even though the Doctor referred to them as Lonely Assassins, although not really so lonely when it suits them) and they had no help in the room, however...
Lights: Unless everyone is closing their eyes when the lights go out, clearly it is not just line of sight but actually being able to SEE the Angels that freezes them, so yes, when the lights go out, even when they are stuck looking at each other, there is no reason that shouldn't free them. IF IT DIDN'T then they wouldn't be able to move when the lights went out either because they would have their hands uncovering their eyes. Even in
Blink this is true, despite what the Doctor says, if it weren't they would never be able to move in groups, but since the first show they appear in clearly shows them doing so, obviously the "quantum lock for eternity" thing is wrong. That or they have zero and I mean ZERO peripheral vision. We are basing what we know on the Angels on the Doctor's knowledge (dialogue), and obviously as we saw in
The Time of Angels and
Flesh and Stone his information is incomplete and still growing. (He didn't know about the images of Angels until he read about it)
As Stark said, it is not about dialogue, but what we observe as what we should take as what is correct.
Statue of Liberty: Hokey? Yes. How does it move? How do any of them move? They are all made of stone, literally made of stone, so why is a small statue moving fine, but a big giant one not? How does it become an Angel? Perhaps a regular Angel can take over stone forms. I mean if they can be a live CCTV image, I'm sure they can manage a big statue.
The only irreconcilable issue is the pictures people take of statues in New York and obviously the Statue of Liberty, and there is probably never a point when someone isn't looking at the thing or won't happen to notice it wandering around lower Manhattan.
Rory: Rory doesn't disappear because he sees his name on the grave stone, he disappears because the Angle that survived the paradox event sends him back to 1938. You could even say if you want that Rory seeing his own tombstone before time caught up and deleted it allowed the last Angel to survive the paradox event and thus created the fixed point that the Doctor can't screw around with, which is exactly what he said would happen when you read your future. Obviously Rory died in New York, but that doesn't mean he stayed in New York by any means. Just that his resting place is there. The Doctor has always been correct about these things even if he was wrong about exactly what the fixed point was at first glance. (Pompeii and his "death")
Also, bear in mind while ages are on the headstone, no dates are. There is nothing there that indicates that Rory actually went back to 1938, the only times that are actually fixed is that Rory died before 2012 and that the EVENTS of the book happened in 1938 that is not when the book is published. (Amy pulls the date out of the middle of the book, not the copyright or publishing dates in the front or rear)
Amy: Amy always knew the Doctor would come back to her and she kept it a secret since she was a little girl. It completely explains how and why she acts the way she does with him.
The second visit to give her hope also explains her adamantly believing in him until he shows back up, despite everyone saying she was crazy.
As to when Amy died or when she went back in time to, keep in mind that 1938-2012 is 74 years. I'm pretty sure Amy wasn't 13 (in fact she should be over 31) when she went back in time so it was further than 1938 if she was 87 when she died. If she had gone back in time to 1938, based on her approximate real age, she would have died in 1994 living 87 years. If she died in 2012 and that was a fresh grave and she used her real age (1989-2020) then the earliest she could have gone back was 1925. I doubt from the look they tried to convey that it was a fresh grave and it looks like it was meant to be much older.
River also visits her to deliver the message to write the afterward to the Doctor, so it's not like she or Rory are trapped in something no one can visit.
New York: Don't be stupid people. HE IS IN NEW YORK. Obviously he can go there, just not to 1938 and possibly just back in time to that point or around it. Doc10 is also covered because he was there BEFORE the paradox in his own timeline. Doc11 also went there before the paradoxes in his own timeline.
River Song: Gah, I really don't mind the character or the interaction or the stories, I just really, really, really don't like the actress in the role. And yes, since she is no longer in custody and a Professor, she is getting close to the end of her 'life'. I imagine they will keep her around until Matt Smith departs the role though.
However if she is a Professor now, he shouldn't be this familiar with her because they are going in opposite directions.
