I thought I'd make a thread to talk about one of the Doctor's most formidable enemies; the Master. Feel free to share what you think about him, your opinions on which incarnation you like the most.
My first story with the Master was Mark of the Rani, but I didn't really care much for him. Though, that was mainly my fault since I'd seen the Colin Baker episodes before really getting far into the older ones. That, and the writing for those episodes wasn't very friendly to newcomers. I didn't know what to think of him. All I knew that he was a fellow Time Lord.
I'd seen a few more stories featuring Anthony Ainely, but he still didn't do it for me. He just seemed like some smug asshole whose only purpose was to troll the Doctor. Then, I saw Terror of the Autons. To me, Roger Delgado was the definitive Master; menacing and sharp, but charming. He and Jon Pertwee's chemistry was amazing,
As for the new series, I liked John Simm. He was a little too psychotic for my tastes, but for some reason I liked a lot of his dark humor. From what we've seen of Michelle Gomez as Missy, she's alright. I thought she'd be a little more calm and collective, but by the end, she reminded me too much of Helena Bonham Carter as Beatriz Lestrange.
So, my ranking of actors who played the Master:
Peter Purves/Geoffrey Beever
Eric Roberts (Yes, that Eric Roberts!)
