All Star Superman has a quite succinct rebuttal to Lex Luthor as a character:

“I could have made everyone see! I could have saved the world if it wasn’t for you!”

“You could have saved the world years ago if it mattered to you, Luthor.”

(I think the book is the superior version, but I do love that the movie adds a sincere “you’re right” from Lex in this scene).
