I think the penguin is really shaped by the characters and the mob context. Spideys rogues gallery doesn't have anything as gripping when spideys removed. Most of the characters also basically revolve around spider man so a story without him needs to find a way to fill the vacuum. Doc ock or lizard would basically just be boring science shows, goblin would be corporate action, or kraven would be nature doc. All of these are pretty boring.
I kind of disagree. it was a good show, but absolutely felt like it could have been anything other crime drama. I didn't feel like there was any real point in making it about penguin.
The Spiderverse movies are (so far) pretty good. Sony could have leveraged that into a franchise universe. Or, they could have run with popular characters (Michael Keaton's Vulture spinoff?). Instead, we get Morbius, Madame Web, and Kraven. 3 back benchers nobody asked for.
I heard Sony is dicking with the last Spiderverse script.
A vulture prequel honestly could've worked. Maybe even just adapting the tinkerer style plot line with the vulture taking out a rival dealer whose much worse than him. Trouble with a parallel world vulture is that hiz dynamic with pete is basically the most interesting part of the character after homecoming and this would remove that.
