Loved the episode. As others have pointed out, it was nice to see the Angles become scary again and especially to see them doing their "potential" consumption again.
But OMG I'm going to miss Rory and Amy. The chemistry between those two AND the Doctor is pretty much off the charts. The little throw away lines, the in jokes, I just don't see how the show can be improved by their absence. Those characters were getting better and better together with each passing season.
Oh well, I'm only a NuWho watcher -- I've only seen the occasional Who classic -- so I'm sure others have felt this way about a companion before, only to eventually find another one to love.
Anyway, great episode. And please don't anyone remind me that Matt Smith's time will soon come to an end -- I can only take so much depression at a time.
