8. Clark Who?
There has always been a certain amount of looking the other way when it came to accepting the reality of a world where Superman and Clark Kent are never in the same place at the same time, yet somehow nobody ever successfully puts two and two together. Superman Returns went one step further by having Clark and Superman disappear for long periods and then reappear at the same time. Still, nobody ever gets clever enough to even wonder aloud why that is. And yet, all of that would have been forgivable, if not for the fact that nobody with significant screen time seems at all concerned about Clark Kent. If they all assumed that he was at home with the flu while Superman was lying in a hospital bed recovering from a nasty Kryptonite stabbing, they could have clued us in. The lack of concern for Clark isn't help by the absence of memorable character moment. In fact, I can't remember even one.
