Okay, I'mma be the weird one here, I guess: I don't read superhero comics, but it's not because I have a problem with superheroes themselves (or their cliches). It's because the execution is often just so...boring.
You open your average everyday issue of a hero comic and it's like:
1) OooooOOOOooo foreboding mysterious scene of mystery-thing occurring...! A weird asteroid falls to earth, or a villain does a little monologue in their little lair, oooooooo. What are they planning, ooooo....?
2) Next scene! Here's a casual scenario. Casual casual casual. Alter-ego of hero is chatting with friends and family. This is obvious setup for the civilian B-plot, because alter-ego of hero is a hero, too!
3) UH OH THE PROBLEM IS HERE! TIME TO PUT ON THE HERO COSTUME!
4) FIGHTS! MONOLOGUES! THINGS! Will the hero be able to win?! (Of course they will, they're the title character!)
5) The day is saved~. Alter-ego of hero learns a lesson from the thematically similar fight they just had with supervillain, and resolves the civilian B-plot. Hooray; the end~
...Now is there anything inherently wrong with this plot structure? No...but when you refuse to do anything even remotely creative with it, it gets old fast.
And it starts to feel like many writers don't really care about making any of the characters engaging or entertaining, because it's assumed that we're already supposed to care about them because...genre.
Why should I like superhero? Because...is superhero. Cool costume. Name is on cover.
Why should I worry about superhero's secret identity? Because...is secret. Secret stressful and scary.
Why should I care about superhero's family and friends? Because...is emotional support characters.
Why should I be afraid of the villain? Because...is villain. Bad guy do bad things.
And so on and so forth. Personal details about the characters that would actually make us enjoy them are treated like lore; things to be spelled out as clearly and quickly as possible so we can hurry up and get to the action. The precious action, valued so highly that nothing else matters...and thus, it has ZERO weight. =/ I like explosions and pretty pictures as much as the next guy, but it takes more than that to get me to stick with a comic.
This is why the only mainstream superhero I've ever really taken a liking to is Spider-Man. He isn't immune to the formulaic plot structure by any means, but...at least he's funny. ^^; He doesn't just occasionally spout a snarky one-liner; he's truly a wiseacre who makes actual jokes and doesn't know when to shut up.
His personality is on full display all the time...and if you just skip over that part of his character or try to rush through it, it's not really him anymore. He's not just a problem-solver with super-powers, he's also a character who is meant to be fun.
And I think better-written superhero stories usually benefit from that-- identifying what a character's trademark is (or, y'know, giving them one...plenty of heroes don't really have noticeable personality traits) and making sure their stories spotlight it.
We want to see the angry heroes use their rage; we want to see the analytical heroes use their intelligence. We want to see the kind heroes show their kindness...not just for a panel or two, but as a recurring element of the story that we can look forward to, a way to always showcase who they are, rather than just what they are.
