Somewhere along the line we read Sun Tzu ...
My Alternate Hero Entity can't thrive in a Universe with Superman comics and Batman comics because My Alternate Hero Entity can't overcome the whatever thing that the customer prefers about those other choices.
So, for my product to thrive, I must destroy yours by any means.
That's some wrong thinking.
There was room for other ideas if they would express them in artful, interesting ways. Would they overcome the big characters immediately? No ... but ... they could compete. They made Swamp Thing ... and Iron Man was supposed to be an anti-hero.
But, come on man, artful and interesting can't be conjured up in a power point slide which is what they kids are learning in college these days. Artful and interesting is hard and requires work. I don't got time for that. I can do ironic, hip, sarcastic, victimology, or false logic. But, artful, sincere, or interesting are not in my skill sets.
Some men just want to see it all burn .... A. Pennyworth.
One could say, they win either way ... the loss of the medium is no loss to them ... they never enjoyed it and the entities they oppose did ... Sun Tzu again.
Destroyed or converted ... same result.
The good news is ... someone will come out with the pulp comics again in a few years with Super Duper man and it will be a nostalgic favorite. I prefer pulp over slick paper and look forward to chuckling over it again.
(I got boxes of decaying pulp in my attic ... I'm good for at least one more lifetime.)
