It has to be said that I am not the only one who would like to see John Simm back as the maniac that we saw in Sound of Drums/ Last of The Timelords. Simm then reappeared in the Tenth Doctors finale but he wasnt given a truly good crack at playing the character in that story, mainly due to the fact he was hardly in it. Indeed, Im sure Simm has got much more to offer in the role of The Master. Maybe he can pop up in outer space for once, menacing some alien race like he did in the 70s and 80s.
