This thread definitely reminds me of one thing though...
Comic books lowkey started falling off when creators stopped writing for the general audience.
Guys like Stan and Jack knew how to write comics for all ages that appealed to a wide demographic.
The problems started with the direct market when companies started only stocking the comics mostly in specialty shops instead of 7-11's and grocery store checkouts that were regularly visited by kids and everyday people.
The characters themselves got ruined when everyone started trying too hard to to have everybody on some Watchmen anti-hero type stuff. It feels like stories rarely about heroes fighting villains anymore. It's either 'heroes' fighting each other over fake moral dilemmas, fanboy writers making their favorite character invincible, or characters blatantly acting as mouthpieces for the writer's politics*.
(* Dealing with politics in comics is cool, when it's handled the right way. There's a time to stay subtle and there's a time to make your point with a sledgehammer, but you always have to handle sensitive issues in a way that's respectful to the characters and most importantly, the audience.)
Cats these days will instantly dismiss every character as corny unless they're some kind of ultra-violent anti-hero that goes around murking everyone. Characters like that can be cool when done right (like Guts for example), but not everybody is meant to be that. You need your straight laced good guys, you need the funny guy, the nerdy guy, etc.
Some of these cats complaining sound like the types who would throw their whole kid cuisine away after only eating the pudding back in school, and it shows. They'd spend the whole day exhausted as kids-- messing their grades up and wondering why they had no energy to play kickball after school--that's because they weren't getting their nutrients. You can't throw your fruits and vegetables, etc. in the bushes just to only eat the sugary treat at the end. We all like that part, but you can't live on that exclusively without becoming flabby and sick.

In the same way, you can't make EVERY character in your story into a Punisher/Wolverine/Vegeta type, because then there won't be a story.
...and that's the big problem with a lot of these new writers and outspoken fanboys these days. They aren't thinking about coherent storytelling or having any kind of functional character dynamic.
...They just want sugar.
