Thor got his power .... without any real work.
Hulk got his power ..... without any real work.
Captain America got his power ..... without any real work,
Spider-Man got his power ....... without any real work.
Fantastic Four got their powers ...... without any real work.
Marvel mutants got their power ..... without any real work.
Superman, Wonder Woman, Aquaman ...... without any real work.
Shazam got his powers ..... without any real work.
Starfire got her power ......... without any real work.
I'm sensing a pattern here.
hmmm
Captain America's "power" isn't the super soldier serum.
Thor is a thousand year old hero with a fleshed out backstory and responsibilities to his people (now a crushing grief).
Iron Man did work for it, and we see it.
Dr. Strange did work for it, and we see it.
Bruce Banner is constantly waging war with his alter ego internally and is hated by the world and in many cases his friends and loved ones, and hates himself for what he is.
Spider-Man bears the burden of Uncle Ben and Gwen.
Fantastic Four, X-Men, et al are outsiders and freaks to society.
Black Widow has no powers, but does have a tragic backstory she carries with her.
These characters have trials, faults, duties, sacrifices. We see them grow in their origin films, become heroes, not just gain powers.
Carol has no arc. She doesn't grow as a person, she doesn't sacrifice for others or the greater good, she has no baggage or guilt or failure to overcome, no meaningful flaws, no relevant antagonist (other than The Patriarchy? lol).
She stands in front of an explosion and then acts like a dick while everything goes her way.
