Series 7 is in the can. In a series that has been extremely uneven, this was a solid ending. It answered some questions and left a few open, but like the rest of the series; it had its ups and downs.
THIS WILL CONTAIN SPOILERS, SWEETIE.
What a way to start the season. I've watched it four times. It gives us a quick glimpse into the lives of Rory Williams and Amy Pond without the Doctor, and then throws us right into the crazy. It also introduces us to Oswin. I can't talk too much about her because that would give away too much, but she is amazing. She's like a female version of the Doctor, but human. She's who I imagine a child between the Doctor and Amy would turn out to be. Sassy, funny, brilliant, emotional, and wonderful. But if Amy and the Doctor had a kid, it would be a little too weird and complicated even for the Whoniverse. She's played by Jenna-Louise Coleman, who is slated to play the Doctor's next companion. How that is going to work out I have no idea, but I'm sure it will be good.
And we are back. This is a much stronger episode than Ep2. The tone of the episode is interesting. You'd think with the setting being the Wild West there'd be more humor, but no. There was more humor in Asylum of the Daleks than this. There's a darkness to the story. You get to see more glimpses as to why the Doctor should not travel alone. It's reminiscent of the 10th Doctor in "The Water of Mars." There's also an ambiguity to the story that I would love to see explored more in different episodes. Does someone's good deeds cancel out their bad ones? That said, I think the best part of the episode is Susan. You'll know it when you see it.
