Re: BvS villain poll
I wouldn't have an issue with Lex being the only "villain" because it's such a new dynamic. The draw is Superman and Batman. A villain is introduced for the sake of giving them someone to team-up against.
What I would not want is for Lex to be the only villain without a physical payoff. If Lex doesn't dawn the battlesuit/powersuit then it has a strong chance of repeating one of Superman Returns' mistakes.
