First, I'm so glad his "wife" wasn't River. Estatic.
Second, wyrd episode, but I think I liked.
Third, still kinda thinking the whole thing is a big dream sequence as far as Amy's concerned, or maybe every-other-episode will be. I mean, if leaving the universe was that easy, the Doctor would have pulled Rose out of the parallel world ages ago - but Amy doesn't know that, 'cause he's never told her about Rose.
Fourth, was watching "The Curse of the Black Spot" before hand and the episode just makes no sense whatsoever. Really. See earlgreytea68 for futher elaborations on this matter. But at least I got my nails redone during it.... so two thumbs up, I guess.
