Benjamin Francis Elliott: BBC America aired the full episode, albeit with oddly placed ad breaks. An ad break DURING a regeneration - not cool. I'm surprised they never just run a set of commercials in the natural pause at the end of the opening credits, reducing the number of intrusive breaks required.
