why? Iron Man is totally human and weak outside of his suit ("Put on the suit!"). Capt. America too to some degree is an enhanced individual, but doesn't really have any other magical powers. He's just strong and fast. Spider-man is a goofy kid.
The worst superheroes are too powerful, like Superman, Capt. Marvel, and Wonder Woman in the last movie (she flies! She's invisible! she's impervious to lightning! She can block bullet! The lasso can do anything!)
Another example is Spider man too actually. The Tobey Mcguire version was great. So was Tom Holland at first. But then each iteration got more powerful. Now Spider man can fly! He can control drones! He is like iron man and can invent stuff on the fly! He has AI! He has killer webs! Now Miles Morales has electricity and invisibility!
It's fun when you think your super heroes COULD actually die.
