I was away a while, but I have now finally finished Series 6.
Night Terrors: Great story, and I enjoyed that it was a standalone episode. Pretty genuinely creepy, I loved the doll house. George was adorable as well, his father was really someone that I sympathised with, and pretty much everything else was well done as well. A very well rounded and enjoyable episode.
The Girl Who Waited: Fucking tearjerker, this one was. Pretty much everything from Rory's meeting with the older Amy was heartwrenching and yet beautiful and those last few moments were some of the best stuff of the show, and I really really felt sorry for both Rory and the Doctor - Rory because of the impossible choice and the Doctor for having to do what was necessary.
The God Complex: While the way that the story unfolded was terrifying and all the actors did splendid jobs, the resolution felt so, so weak to me that it left me really underwhelmed. I did like Gibbis, though, he had some of the best parts of the episode.
Closing Time: I'm starting to see a pattern - whenever the Cybermen make an appearance, the episode is pretty weak. I did like Craig's reapparance, but he was better in The Lodger, anyway. The way that the Doctor spoke with Alfie was pretty awesome, though, and those final minutes were goosebump-inducing.
The Wedding of River Song: Amazing finale. I loved how time was collapsing and everything happening at once, and how the concept of fixed points was expanded on. The Silence were terrifying again - some of Doctor Who's best villains, of all time. Madame Kovarian's death was pretty amazing as well, and the resolution of the whole arc was amazingly simply yet sooooo clever, though I am wondering how a Teselacta copy of a person, which is basically a robot, can begin to regenerate? Anyway, those last few minutes were intriguing - does "the fall of the Eleventh" refer to Matt Smith's final episode? I guess it does, but only time will tell.
