Hal, he's the regular guy who's given responsibility, learned ethnic lessons from the right people, has real flaws, and lets loose when screwed. When he became Paralax, it was so stupendously handled I didnt care much about Kyle or his "last of the corps" shitic, I just saw a hero turn badass out of personal choice, and for reasons valid and reasonable. Hal could have been a great life lesson in power corrupting absolutley.
But Geoff likes Hal, DC likes Hal, and the fans liked Hal, so they paid no attention to people who liked Kyle and just made a bitch he was never represented as in the title.
