I said, ‘What about at the end of the movie we do a scene where there’s a crate full of kryptonite delivered to Wayne Manor. Everyone was like…‘Okaay.’ Once you say it out loud it’s a problem because you can’t unsay it.
If you’re going toe-to-toe with the son of Jor-El, you better come correct. For his climactic rooftop brawl with Superman, Batman outfits himself with a reinforced mech-suit equipped with strength-augmenting armor and, yes, kryptonite. The design resembles the one used for the confrontation between these two in Frank Miller’s The Dark Knight Returns.
He’s on the verge of being swallowed up by the anger and the rage that we see haunt this character in the other manifestations of it. But this guy is further down the line and has become more embittered and cynical.
