Stolen Earth (spoilers for this one)
Okay so last year at the same time, I was pretty happy with the show, I loved "Utopia" and "The Sound of Drums" and was hopeful for the last episode and I was pretty disappointed. I mean RTD is pretty good as far as show running, characterisation and stand alone episodes are concern but the man can't wrap up an epic plot to save his life. He always pull some kind of deus ex machina out of nowhere.
Long story short, I've enjoyed these last 2 weeks episodes, really liked them (Catherine Tate rocks) but I fear what they gonna do next week. That being said, afraid or not, I want to be next week already :)
And I don't think Ten is gonna regenerate, something's gonna happen probably involving the hand and possibly Donna.
It would be really hard to keep the lead on on such a major casting change and if they pulled that off (shooting an entire episode with a new Doctor without anything leaking) well kudos to them.
