Controversial opinion: I absolutely detest it when Superman is instantly dismissive, overly mean spirited, and just overall an unnecessary d!ck to Lex Luthor. I know, I know "but Lex is a bad guy, and has done super bad things in the past, so Superman is right to be mean to him." I'd agree with you if Superman were predisposed to that sort of grudge holding, but he's just not. And it's not because "dude he's Superman" (well it sort of is), but it's actually more because Superman--Clark sees the bigger picture regarding Lex. The Lex and Superman stand off is made possible and interesting by the idea that our hero actually wants to ultimately see our villain become a better person, and our hero totally believes it's possible. Clark doesn't just hate Lex like an action movie star hates the bad guy. When Clark looks at Lex he sees proof positive of inherent human potential. Every time Lex makes a device that can crack open dimensions out of an old watch and some cooking foil, I gotta believe that Clark's has a feeling of genuine wonder and "wow he really freakin did this" to him. So whenever I read Lobdell, Jurgens or whatever 90's writer have Superman yoke Lex up even before he has the facts, I gotta roll my eyes. That's missing the point, imo. And whenever I see them describe Lex as irredeemable I think to myself "so then did Superman just straight give up? I thought he wasn't in the habit of doing that."
That said, Superman/Clark can and will get extremely frustrated and mad with Lex, because the longer Lex is the Lex we know then it's spitting on the idea that humanities potential can be used for good. Don't get me wrong, I enjoy those scenes where Clark burst into Lex's office or hideout with righteous fury, but it CAN'T come from that whole cop shaking down a prep angle. I like Superman who can sometimes trick Lex into doing good or the one who can deflate Lex's ranting with a smile and a clever string of words. Sometimes Clark gets to the point where he's boiling mad, but that shouldn't be his default when he sees Lex.
So you can imagine that what's going on in Action Comics right now just isn't my bag at all. It actually makes me cringe a bit.
Opinion 2: Lex is basically a semi regular supporting cast member who doesn't have to serve as the villain every time he's in a comic.
