I feel like, and this is a weird thing to say, that DC is somewhat embarrassed by / ashamed of the popularity of at least some of their properties, as if they somehow 'aren't serious enough' or 'not real art' or some argle-bargle nonsense.
They keep trying to update them and 'make them relevant,' in the process somehow surgically excising anything *entertaining*, or even, some cases, even *human,* from the properties. At least a few times in the last few decades, someone has come along and tried to reinvent Superman, a bright hopeful *smiling* inspiration to the world, as angry and alienated, a red-eyed, scary, scowling demigod. The same sort of mindset goes into trying to turn Diana, an ambassador of peace to 'man's world,' who the song says, 'can win a war with love,' into a sword-wielding head-chopper-offer warrior badass (with an army of bees? Whatever.).
Yes, stories like the Watchmen exist, that can take the 'funny book' format into bold new thought-provoking directions, but, here's the thing. That was a work of genius. Not every attempt at 'deep' storytelling since then has succeeded on that level. And not every property or character or setting lends itself to that sort of story (heck, they had to invent all new characters and set them in their own world to make it really work!). And even if there are plenty of geniuses out there, and possible thought-provoking storylines waiting to be told with just about everyone, that doesn't mean that *every* story needs to be shocking and edgy, racing to out 'mature' or 'controversial' the last one. Some stories, indeed, I'd argue, *most* stories, just need to be entertaining. It's not rocket science. I don't go to the comic store expecting to read something that changes the world. I just want a good story, and don't expect (or want!) *every* story to be attempting to escape the horrible curse of being 'just comic books' and becoming some sort of high art.
But as for the Legion, specifically, I love the bright colored clean future depicted in the older stories. The real world is gritty and depressing enough. I don't want to read about 1000 years in the future, Earth being a few city-habitats floating in space, the planet itself long destroyed, or various other dystopian things. Threaten the hell out of that idyllic future. That's what heroes are for, after all, stopping that sort of nonsense! But don't wreck it.
'Cause if you, as a writer, do wreck your heroes setting and make it all dark and hopeless, that means that they already failed.
And that's not the story I came to read.
