On that note, I would've liked to have seen The Master as an anti-hero. I'm specifically thinking of John Simm's incarnation rather than the EVIL MAN WITH DODGY BEARD predecessors. Inspired by the Doctor trying to make him realise it's just the two of them left and there's no need for any of this. Then the two of them go off, travelling the universe, and The Master isn't afraid to solve problems like a badass, and there being conflict between him and The Doctor for the way he does things. The Doctor does The Right Thing, but it's not as damned effective as The Master's solutions. Maybe the Doctor's female companion could find the bad boy attitude sooo dreaaaamy~ too for some added tension.

Not really relevant now that the Time Lords are back now though but ah well.
