I don't read a ton of super-hero stuff. I really find the genre too optimistic; the idea that one great person can save us turns me off.
Rectifier is a little different. Here are people with not just minor flaws but major problems, suddenly handed incredible power. Rectifier is just a homeless guy whose made bad choices (including horrifying choices). He struggles with his very worth as a human being. When an alien implant gives him the power to manipulate electricity, he understands it at a technical level, but also resents it almost as Thomas Covenant resents his central role in Stephen R. Donaldson's universe. Actually, we can map this story onto that one without stretching much.
Rectifier doesn't so much save the world as show us how troubled it is, not only in fictional Bay City but today. He makes visible some of the invisible people. That he does so while dodging crime syndicates and battling other super-powered people doesn't detract from the close-up look at the humans beings we choose not to see every day.
Well done.
