I enjoyed his work on Green Lantern and to a lesser extent Guy Gardner (Reborn being the highlight). I didn't really care for his JLA run and I'm not familiar with much else he's done.
I hate when someone whose work I admired turns out to be capable of something like this. I try not to sit in judgment of people but when it's something like this it's impossible not to. I'm all for delete the guy from the history books but it's hard. I actually own some pieces of Green Lantern original art which were written by this guy. Do I have to throw out the fine work of the penciller and inker because this guy was attached to the project?
Disappointing. Innocent until proven guilty, I suppose.
