Superheroes comics (capeshit for short) were designed to make as much money as they can off kids, so they're based on always referencing a previous issues, so that the readers are enticed to buy even more comics, or to keep reading them so that they're not thrown off the plot.
What makes a good comic isn't the franchise or the character, but the writer. Some eminent names in the field (with some of their best pieces) are:
>Alan Moore (The Killing Joke, Watchmen).
Writes fantastic villains, a bit verbose but not too hard to read. Weirdly has to include a rape or rape attempt in every story. Loves the occult, always do a lot of research to do his comics (every character in League of extraordinary gentlemen comes from a 19th century novel, even never to be seen again bystanders)
>Warren Ellis (Transmetropolitan, The Authority).
One of the few to have refreshing diverse casts in his comics, of genius antiheroes fighting against enemies much stronger than them.
>Brian K. Vaughan (Y the last man, Saga)
Really good at unique storylines and universes, surprising plot twists and entire one-case pages of people fucking
>Mark Millar (Kick-Ass, Wanted)
Responsible for most comic-based violent movies. Very edgy and not too clever but fun
>Grant Morrison (Arkham Asylum, The Invisibles)
Sworn rival of Alan Moore and (for real) chaos sorcerer. Reading his works will either open your third eye or leave you a bit confused. His stories are as researched as Moore but he's suspected to invent most references.
>Garth Ennis (Preacher, Hitman)
Storylines involving God (or lack of), villains doing really trashy actions, and somehow always ending up talking about the irish conflict (he's Irish)
>Neil Gaiman (Sandman, American Gods novel)
Big fan of mythology, his works are poems best described as "Grant Morrison but actually understandable". Rather low level of violence, A Dream of A Thousand Cats is a very good way to show comics can be great ( https://imgur.com/gallery/VBHoG
>Mike Mignola (Hellboy)
Writes and draws very well, maybe not as deep as Moore but much more stylish. Mainly known for Demon Indiana Jones vs lovecraftian shits & Hecate
>Frank Miller (Dark knight returns, Sin City)
Stories of really strong men that hit really hard their puny enemies while getting also hit really hard. Very stylish (don't watch the movies)
All of these authors dabbled in capeshit to start their careers (doings some great works) but blossomed when they could put their hands on their own universes. Superheroes get their reboots of varying quality from time to time, word of mouth will sadly be your best guide here. Never hesitate to start reading an off-putting series, you'll get more good surprises than bad ones
