Justice League Unlimited on the Cartoon Network just keeps getting better. I think the main reason is that they get writers from the comic book industry who, for the most part, stay true to the original characters and attempt to integrate what's best about the comics into the series.
Alan Moore and Frank Miller changed the landscape of comics by injecting some postmodern realism into the mix. For instance, if there really were heroes who were that powerful, do you think everything would be just hunky-dory between them and the governments, especially the superpowers like the US?
And that is one of the themes that they've been playing upon this season. They've also been using many other of the DC Universe's characters. They've made especially good use of the "Charlton" heroes, (those characters which were created by Charlton Comics, were subsequently bought by DC and integrated into the DC Universe).
Steve Ditko, a Randite, created two characters -- The Question and Mr. A -- as Rand inspired superhereos (arguably, these two are the same character, just variations on a theme).
Alan Moore, when he did his groundbreaking Watchmen actually had the Charlton characters in mind. But DC (who published both Watchmen and owns the Charlton characters) wouldn't let him use the characters because they were then integrating them into regular DC continuity after the Crisis on Infinite Earths. So he changed them; Captain Atom became Dr. Manhattan; Blue Beetle became Nightowl, and The Question/Mr. A became Rorschach.
Rorschach was still portrayed as having far-right (near anarchist) politics; but Moore made him into more of a John-Birch type crackpot than a Randite. Recently Frank Miller featured The Question prominently in his sequel to The Dark Knight Returns (not as good as the first, but still worth the read) at his Rand-quoting finest.
Anyway Justice League Unlimited is doing a great job of presenting a Miller/Moore inspired Question. He quotes Ayn Rand, and is also a right-wing conspiracy buff. From their episode "Question Authority," The Question actually gives the "A is A" speech to Lex Luthor.
The Question: Everything that exists has a specific nature. Each entity exists as something in particular and has characteristics that are part of what it is. A is A, and no matter what reality he calls home, Luthor is Luthor.
