OMG, that would be totally amazing if it was a different version of the Doctor that comes back in the forest. And totally makes sense, because it did seem like he walked away, but then all of a sudden he was there again. I don't know what's so important about this episode that would make the Doctor need to revisit it though.

Yeah, I didn't like the Forest of the Dead rip-off either. Or the changing of the fact that the angels only freeze during the "act" of looking at them. Ten said it was a "fact of their biology, they don't exist when they're being observed." So for them to freeze when Amy had her eyes closed bothered the crap out of me. As for including the TV audience in the blinkers... I never thought of it that way. I just thought they were being incredibly stupid and lazy by deciding not to kill Sally right away.
