I don't really follow Millar the man. I like his contemporary take on things. His writing is anti-old skool and stodgy tradition. He generally pushes the boundaries on things. Some of that is hype-driven, but some of it is innovative.
The torture of the old Doctor with a cattle prod is a good example. Another book would have made a big deal out of the morality of it. Millar just makes it a standard tactic for a former black ops superhuman. It demostrates that the line between "good" and "evil" is very blurred, and says more about Midnighter's character than a dozen school bus rescues by Spider-man et al. ever will.
