Right, SPOILERS, of course. Won't hide-text 'em since you'd know better.
Holy bait-and-switch, Batman! When Mels first showed up, right before she climbed out of the car, I jokingly said "Hello, sweetie." Looks like that instinct was right. The whole "Kill Hitler" thing didn't last very long and...I'm oddly very okay with that.
I have to admit, I didn't see River being a villain (if only temporarily). Really interesting ways they handled her regeneration, though, like getting shot by Nazis. Also, I flipping loved the Shrinky Justice people. Not their real name, yeah, but still awesome.
If I had one complaint, it was how the answers we got were sort of...just given. Like the Silence. So I'm confused, now. Is The Silence still those freaky grey alien guys or is it the organization we saw in the last episode?
But yeah, overall? Loved it. Can't wait for next week. GERONIMO!
PS: What'd everyone think of the trenchcoat The Doctor wore? I wasn't entirely crazy about it, but I dug it.
