The only teenage adjacent character that ever was worthy of being in the JL was Firestorm, and Naomi isn't fucking Firestorm. She's not even Vibe, if we're comparing her to horrible JL members.
Also, of course I never read her book. Bendis is a shitty writer, and I don't even read books he writes nowadays about good characters. His teen heroes are even worse, its like reading the old Bob Haney Teen Titans comic, an old man who doesn't understand "the kids today" trying to write teenagers. This is the man who has devolved so much as a writer that he ruined Jessica Jones years after he created her, and Naomi is shit from her basic premise, while at least Jessica Jones was a good idea that Bendis had and took awhile for him to ruin. Naomi is just teen idiot #3456. DC usually does teen heroes better then Marvel, but naomi is 1000% just a generic Marvel teen hero, like Ms. marvel or (more accurately based on her backstory, I guess) America Chavez, done in DC.
Also, after he ruined Legion of Superheroes, Bendis can just fuck off forever. I almost felt like burning my fucking New Avengers TPBs after he did that shit, he's retroactively ruined even his prior good work in my opinion. He's not as bad as Tom King or Scott Snyder, and he's a different kind of bad from them, but he's still one of the worst DC writers.
