Comics books are supposed to be cheap, disposable entertainment. Unfortunately, the comics books of today are almost completely different from those I knew as a kid. DC editors and creators like Julius Schwartz, Elliot S! Maggin, Mort Weisinger, Curt Swan, Dick Giordano and Joe Kubert were real men, grounded in the real world of bills, wars, and family life. Many were also religious, and worked the general concepts of religion into their work.
(To be fair, Marvel had many religious people such as the incomparable Jack "King" Kirby on staff; I used to refer to Marvel as the Jewish comics company and DC as the Catholic comics company.)
Of course Marvel had gods as heroes (e.g. Thor, Hercules), but in the DC world the God existed and even intervened in human affairs on occasion; for example, DC's the Spectre was the Wrath of God personified, and DC's Green Lantern went to Limbo after he died.
(Superman was raised as a Methodist by the Kents; I'm not sure if he still attends.)
Today's American comic books industry is run by a different breed. Many of the big-shots at DC and Marvel are '70s comics fanboys who have, er, a less traditional view of the world than the folks that made the funnybooks before them. Now, there are lots of good people that work in the U.S. comics industry today, and there were plenty of drunks, wifebeaters, and crazy people making comics back in the old days; the difference between today's comics creators and those of the past is that back in the old days the drunkenness, violence, and insanity were not celebrated in the pages of the books.
Case in point: The hottest creator in comics today — and I mean the absolute darling of comic fans and New York literary critics alike — is a bearded Brit known for "his signature themes...: information overload; cynical, burnt-out adventurers with hidden streaks of compassion and even sentimentality; the erosion of conventional societal taboos; posthuman technology run amok; a dysfunctional relationship between, on the one hand, human consciousness and, on the other, technology and culture; the exploration of the inherent contradictions of transhuman philosophy; protagonists with substance addiction problems; an urgent desire for utopia in the face of overwhelming dystopian trends; and an outrageously extreme sense of humour". He had a big success a few years ago with a series about a team of "uncompromising left-wing superheroes" who take over the world and impose their version of Utopia upon it; and another in which "homosexual doppelgangers of Superman and Batrman" fight against the government which discriminates against their love. So much for Truth, Justice, and the American Way.
Anyway, I mostly write for a living these days. I'm planning on doing some comics again in the near future, but I doubt it'll be for any company that publishes American superhero comics. Sic transit gloria mundi.
