Actually, one of the greatest Batman stories ever told is Batman: The Dark Knight Returns, by Frank Miller. There is an epic Batman vs Superman fight in that comic for many of the right reasons.
(I say “many” because there is also a severe anti-Reagan thread there that is downright ludicrous, but - it’s a comic - so I just pretend it’s a really villainous president like Obama.)
Yeah, that was a terrific series. It was politically-slanted, as you say, but amazingly engrossing.
I get the feeling the upcoming movie won’t exactly be cerebral.
