Lex doesn't want to kill Superman, once armed with the extra kryptonite he could have done that himself. He wants to destroy the lie that Superman represents, that power is innocent, the framework of Lex's childhood beaten in to him by his father. If that's thin then you must hate the whole Batman persona because his life was shaped by an incident whereas Lex's was shaped over years.
The destruction of Metropolis isn't enough of a motivator, that would just make Lex as interesting as Ronin or some other disposable villains on screen lately.
Right, cuz 1 or 2 lines about his father using fists on him is great motivation and better than Batman. Again, it's hard to take your posts seriously when talking about characterization, when you were the one who said Batman has no moral code in the comics, that he's a criminal, doesn't care about helping others.
Getting hit by your father shouldn't make you a psycho who wants to be a God, wants to kill other people, creates monsters to....wait a minute...you said Lex doesn't want to kill Superman? I guess we watched a different movie because Doomsday was created for what? To get the job done if Batman couldn't. He screwed with Batmans head so he can get angrier and want to kill this alien off. If he won't do it, the devil will. This is your doomsday. That's what he says to Supes.
Everything is really vague with Lex. He talks in riddles, and in the middle of that gibberish, he drops a line about abuse. Paper thin motivations for wanting to kill people. He has his goons kill people at any cost, throws Lois off a building just cuz it's fun. Doesn't matter if she does, if she doesn't, it's because Superman caught her. He knows Bruce's identity, Clark's identity and we're just supposed to say "oh it's fine, it's the first time we met this character, spent a half hour with him, but he's smart I guess?". Lazy stuff right there.
He's not a real character. He doesn't feel real. He's not believable. Lex from the comics if translated well, would feel like a real person and have motivation that the audience could understand on the surface. A dynamic character. And his motivations would tie into the overall story that begun with MOS. But nahhh, we'll settle for this random guy who happens to have his own weird family problems that we don't give a crap about. And he's gonna use it to get what he wants. How is that better than the Lex everyone's been suggesting??
This Lex and Doomsday are some of the worst villains in the history of this genre on film. And they're both in the same movie. If you add Batman as a villain, he makes three. Like someone said, Bruce Wayne in this movie is the most accurate depiction of Lex Luthor on screen. I've said that Senator Finch behaved like how Bruce should have at times. As Batman, we get Rorschach in a different costume. We get a rich ***** version of Edward Nygma (who Eisenberg should have played) instead of Lex. We get a variation of Superman that feels more like Dr Manhattan. Wonder Woman is all surface...good looks/ass-kicker. Everything is so ass backwards it makes my stomach turn. But the visuals are cool!!!!!!! Right!??
