Amy's Choice: not a bad episode. A little too reminscent of Turn Left (and VERY reminiscent of The Forgotten, a comic miniseries, but I assume that's coincidence as from what I gather most people who work on the show don't even know there's an American comic series). The twists were a little obvious, but well-executed.
Possibly most interesting was the "What's his name?" callback. First of all, this is [spoiler]the Doctor himself[/spoiler] hammering on the Doctor's "Trust me" double-standard with Amy, something I've noted before as significant. And secondly, of course, it's another allusion to the Doctor's name.
His line to River in Forest of the Dead was something like "The only way I would ever tell anybody...the only way I COULD..." Now, I've been figuring the rest of that sentence is "...is if I were dying." But the Dream Lord is indicating that that's not the case (or perhaps that the Doctor doesn't mean "could" in a literal, physical sense; he could simply mean "the only way I could bring myself to do it"). Don't know, but I'm sure this isn't the last time we'll hear about it.
(Have I floated my theory yet that the Doctor has to "die" to break the 12-regeneration barrier?)
Anyway, it all worked out pretty well, and seemingly resolved the love triangle AND elevated Rory to a higher status than Mickey's perpetual sad-sack also-ran. I'm hoping he hangs around for awhile.
