Problem with the format of "marvel characters" (and dc ones) is that you have so many "takes" on the character, that is virtually impossible to actually define what said character is or should represent.
To an author the character is gonna be all about violence, brutality, guns, blood, etc, etc. To other, he will completely flip the style and focus on a more soul conflict kind of narrative, etc.
These comic character are "everything" and "nothing".
Which is why I don't find them appealing anymore.
