I dig Kraven, but I don't trust Sony at all. They just really don't seem like they know what the hell they're doing. Or maybe they just don't care? I know there are legal and contractual hurdles they face but still ...
That they're building toward a possible (but probably unlikely) Sinister Six movie is hilarious. Setting aside the fact that they still don't have a Spider-Man, they're taking every villain and making them anti-hero types. So are they going to be a Suicide Squad-style team of cool bad guys fighting someone/something even worse?
They're not making "sympathetic" bad guys as character choices, they're doing it because they don't have the will or ability to make a movie about the actual good guy who is supposed to be in these stories. So the bad guys have to be the good guys in their movies. (Yes I know Venom and Morbius play on both sides in comic lore but I assume Sony is going to stay on this track with Kraven and others...)
It's a fascinating bass-ackwards way to try to build a universe. And it's been kinda hilarious to watch.
