I was dissappointed that they "killed" the Master but at least there's a possible way back. The scenes with the Master in the Doctor's arms were touching.
And I love the whole Capt' Jack/Face of Boe thing!
Mind you, I love Captain Jack. Such a great character!
Easily the best episode(s) of the series. I still like the idea of Tennant complaining about the fact that Simm had a bigger sonic screwdriver.
