Character Surprises.
To borrow from Kris;
Who, when you thought they'd be shitty, has surprised you in a good way, or has really grown on you?
I'll go ahead and say Norman Osborn. I never really had much against the guy, but he always struck me as someone who would never have impact. Just a rogue gallery piece of fodder, but now he's really achieving the title of one of Marvel's best villains I think.
