Re: The "realism" thread
Well, there were the robots Kal-El built to resembled Superman. I know Clark and the robots have appeared at the same time. That might be enough to dispell the thought. But the other coincidences, you are right on. A pair of glasses is a lot to hide behind when the coincidences start piling up.
Those glasses should have had a holo-projector built into them by his Kryptonian parents, so that it throughly changed his appearance to resemble a blonde, skinny, 5'2 guy. That way, the resemblance isn't an issue.
