Waters of Mars Review (MAJOR SPOILERS)

I waited soooo long for this to come out, and now i have to wait forever for the Christmas Special (The End of Time) too!!!! :( but it was great! Course, at the very end, the Doctor was totally out of hand and obviously had some serious issues... i'm sad and happy because of the end at the same time. I'm happy because the girl whose life he saved who was supposed to die, killed herself, and that needed to happen. It was one of those things where you're normally yelling at them to do the right thing to set time right but they do the wrong thing anyways just to save themselves, only this time she DID THE RIGHT THING to save the future of humankind. I was so happy because of that. But i was sad cuz Adelade Brooke (that was her name) was a really cool, awesome character and you didn't want her to die. But i guess that if she hadn't died I wouldn't think she was such a great character, so I guess it's best this way. The Doctor, though, had some serious issues right there at the end, being all "I'm not a survivor, I'm a winner" and "The Time Lord victorious" and suchlike, and you could tell he wasn't quite his normal self. He certainly wasn't acting like the main character/the good guy. Then Adelade kills herself and a Ood shows up and he's all like, "Is it time for me to die?" and the Ood disappears. I think it was Sigma but I'm not sure. I think the Master showing up in the Christmas special will remind him of what he doesn't want to be and set him right--in any case, his regeneration ought to fix that. There were a couple funny parts, like when the guy tries knocking at the door. Some semipsychic lady told him that "he will knock four times" before the Doctor dies (coincidently, that's the length of the drumbeat in the Master's head) and the Doctor's been all like, no one's knocked four times yet so i can't die. So this guy starts knocking at the door and he gets to three knocks and the Doctor goes "You're stopping right there!" and electrocutes the door and therefore the guy. Also there's that part at the beginning where Adelade's all like, "State your name, position, and intention" and he responds, "The Doctor, doctor, fun." Not exactly what you expect from a visitor on uninhabited Mars ;D
