Oh, God. I am so tired of this proposal.
Again, maybe if the films which showed him in rubberized armor
hadn't done well, they might look to bring him closer to the Superman knock-off suit that so many of you love. But they did-all except one, which told the studio not to put him in a blue suit with nipples. And because the movies
did do QUITE well, there is no logical reason for the studio to change its approach to Batman's look. Except, of course, to appease fastidious internet fanboys who will still rush out to see the next movie in droves no matter what he's wearing.
And once again, think for a second & be honest. Take your desires to see him in grey tights out of the equation for just a minute. If you had tons of money & resources, and found that your last battle-suit didn't quite offer the degree of protection that you needed, would you
really be thinking "Man, I need to cover this up so they can't see my weak spots" rather than "Okay-I obviously need to find a way to upgrade this so that I can have mobility
and protection." Because the former kind of invites your enemies to just attack the places that were vulnerable before. Or just keep stabbing & shooting at your body, hoping to find one.
