That.Rocked.
Excellent episode all the way around. Was a bit concerned that the preview seemed a bit too much like the movie Pitch Black, but in the end was not all that similar.
Excellent pseudo companion. Too bad she's gone. I really liked her.
And nothing is cooler than a flying double decker London bus!!
I give it a 10 out of 10. I really cannot think of one thing to complain about.
Oh, and excellent foreshadowing for the change in Doctor.
