Lke Jack Nicholson/Heath Ledger in Batman, John Simm totally was the star. He made David Tennant look like Colin Baker in the Dr Who stakes. Every bit of screen time he had, was classic. It's always more fun to play baddies and he needs to come back to this show ASAP. The Master has always been the No1 Dr Who baddie- period. However compared to John Simms, The previous actors come off as Dick Darstidly gone wrong! I have worn out my VHS seeing his scenes. Don't forget the Scissor Sisters Scenes- very funny and when regenerates- pure quality. Even when he dies, he refuses defeat. Please resurrect his character, as you need a flamboyant pyschopath with a taste for camp retro themed disco music on Saturday Evening TV!!!!!!!!!!
