The music WAS good, but I just felt it was too loud. As for the Master. At the end of an episode of Doc Who confidential, DT said somethig like "Face of Boe was right, but so as the Doctor." hmm.
My only theory is that there must be...another Doctor. The Master taken over one of Doc's future regenerations, anyone? Valeyard type thing? Jeez, I don't know why I'm getting into all this! What's gone wrong with me?
