My point is you seem to be talking about comics from a superficial point of view and are screaming to the wind about things that can be reinterpreted and used in a variety of ways both bad AND good.
Bendis fucked up with Miles, yes, but the character isnt inherently flawed on a conceptual level. Teenager who gets bit by a spider while Spider-Man has already been active for years witnesses his death in an act of self-percieved cowardice and struggles to fill his place is a genuinely interesting concept, it mirrors Peters origin while adding the twist of having to live up to the previous Spider-Man.
The reason Bendis fucked up is because thats all he did with it, it was just that, and nothing more. Miles was very bland and had little in the way of his own elements, which the movie corrects by giving him a different kind of focus than Peter (Peter is a scientist, he tinkers with gadgets and studies chemistry and whatnot, very academic, while Miles is intelligent but focuses on art and self expression). Plus that fucking garbage nonsense of Peter coming back to go "HEY YOU'RE SPIDER-MAN NOW, BYE". The movie does it better in that everyone thinks he's dead weight until he takes the leap of faith required to embrace and be Spider-Man, only fully earning their respect when he, on his own, gets to the collider and holds his own against a few villains.
Also Peni Parker is mainly redesigned around a different art style gimmick, she's the anime to noirs black and white zipatone dots to hams looney tunes, its not meant to pander so much as to be a visual sight gag.
Also theres no tumblr pandering, visually its stunning both in static shots and in motion (even on the camrip i saw its beautiful).
Also Sony has made good movies before, the problem is mainly the producers shitting the bed trying to create a franchise like taking the pin out of a grenade, its why Spider-Man 3 failed, why ASM 2 failed, and (one of like 10 primary reasons) Ghostbusters failed.
