I thought he was fine as Lana's boyfriend in Superwoman, but nothing special. I figured he'd have shown up in Bendis 's comics, but he's still MIA despite a few different opportunities to have him show up.
My guess there's a plan for Irons, because, with the character getting some renewed exposure in the Reign of the Supermen movie, DC ain't going to just let him sit in limbo for too long.
While being Superman's resident super-scientist & tech guy is pretty obvious, I think more could be done with him.
Any ideas?
