Not to troll but....
I'm not a Hal fan. At all. I think he's bland and his best stuff is when he's stuck in a very specific time period (50s-70s) and his time as Parralax was great (even if the way of getting there was hamfisted) since DC lacks a good Magneto esque villain.
But I'm open to being proven wrong, so please tell me. What makes Hal so cool ?
