I think deconstruction is less a "death throe" and more a response to content in a genre becoming stale, cliche, and increasingly riddled with insultingly obvious plot holes -- case in point, literally every DC-based movie other than Batman Begins and Wonder Woman.
I feel like this problem is easily fixable if they just moved on from the stale duopoly of Marvel/DC already.
Look, deconstructions can be great. Worm is a deconstruction too, in many senses, and I enjoyed it. Watchmen and The Boys, both deconstructions, were good and enjoyable, although not the kind of material that will leave a lasting impact on me, personally.
But I still have plenty of room for traditional, "standard" superhero play. Just not Marvel or DC. For crying out loud, how many times can you chew through the same characters, reboot exactly the same storylines over and over again... how many, say, Dark Phoenix Sagas did we have by now? Original comics, ultimate Marvel, X-Men 3, the new X-Men, the 90's animated series... I bet everything I have that I've missed a few. I liked Spiderman, I like Iron Man, I like a lot of other characters... I don't like them enough to keep seeing stories and variations on them, by different actors and writers, decade after decade, especially when they rehash the same story slightly differently. No, fuck that. Only in the comic book industry such a thing is even conceivable. It's a dead horse, just shoot it in the head and move the fuck on!
That's why Worm was such an incredible breath of fresh air to me, why I really liked One Punch Man even though it's, at least in part, a satire, that's why I keep looking for books in this genre (so far only Sanderson's Reckoners trilogy has somewhat scratched the itch, although it's definitely a deconstruction rather than a straight example of the genre). Give me new plots! New characters, with their own personal lives, struggles, rogue's galleries! New global threats that these new characters will unite against! I'm ready, come ON!
