It really all the depends on the intentions of the creators. Batman and Spider-man have been deconstructed back and forth, inside and out. Sometimes to unrecognizable and unlikable lengths. You may even say that it sometimes doesn't stay true to the spirit of the original creation and that's ok, because it's all about exploration about a character. Every creative mind would love to tackle any of those characters and try to make their own spin on them.
That's essentially what this Dante seems to be exploring. How does he become that dude that everyone likes? Who is that person that's so powerful and cool, was he always like that? In my opinion, this is an origin story that tries to give something more to what was already there via developing the character from scratch. I mean, they sure are keeping a lot of story elements secret still.
It might fail or not, who knows, but it sure is interesting to see. I don't know, your point is kind of skewed, but I get that you don't like him and hold the original very dear.
