re: Eisenberg's Luthor vs. Leto's Joker

The key to fighting Superman, outside of kryptonite, is to use his morals and ethics against him. He would save a continent, AND save a puppy across the world, if he could; and you have to force him to figure out how to do both, and then the bad guy too.
Because he will instantly win if you don't force him into an ethical dilemma.

Problem with the movies is that they've already made him concede his ethics at times, without showing us the immense power he has. He's not Superman, he's fast and strong flying guy. There's really nothing that the real Lex would find annoyingly wholesome about him, he's just a powered up dude that even Batman mistrusts. That just isn't working. Might be good for CGI and angst, but it isn't TRUE Superman.
