I think most of the episodes this season would have benefited from being about ten minutes longer, and this one was no exception. The ending sort of felt rushed, as a lot of them have (this problem was especially egregious with "The Power of Three", where the Doctor basically waved a wand to solve the problems of the episode. Then again, the conflict wasn't the central point of that episode anyway, so it's not a particularly big deal).
In this case I felt like the episode just sort of... ended. There was an unfilmed scene with the Doctor going to visit Rory's dad which I really wish had been included - the ramifications of Amy and Rory's departure basically aren't explored at all. They couldn't really have plausibly cut anything from this so that's another part of the reason I think the episodes should have been longer. (Of course, they couldn't have run them on BBC America in a normal one-hour block with commercials, and running episodes on BBC America with commercials is a large part of the reason the series has such high production values, so I guess it was inevitable).
That said, the episode definitely hit me like a tonne of bricks anyway despite its flaws. One of the most devastating companion exits I've seen, probably rivalling Doomsday and Journey's End.
And yeah, Karen Gillan is pretty much one of the most beautiful people in the world so yeah. Then again Jenna-Louise Coleman is pretty damn attractive herself
