Because I Personally say No because then what was the point of the ending in No Way Home? The whole point of NWH’s ending was for Peter to at least try to create a life for himself that doesn’t revolve around them, or frankly even anything from before he met Mysterio. For goodness sake, they killed off May. They’ve got to let the consequences of Peter’s decision sink in for a movie at the very least.
‘But Tornado, they brought back all of the Avengers after one movie!’
Yes, because the MCU actively revolved around them. You can’t run a franchise without half of its main characters. Meanwhile, Spider-Man has never been that dependent on MJ. Is she his most famous supporting character? Without a shadow of a doubt. However, she’s never been involved in every single stage of his life. They didn’t even meet until university in the comics.
‘But Tornado, Zendaya’s too bankable for Sony to pass up on!’
Sony has its own agenda, but sure, it’s not as if they’ve been trying to get a Black Cat movie off the ground for years? Granted, there’s a difference between that and making her an MCU character, but we can cross that bridge once we arrive at it. There are also a whole host of love interests from the wider universe that Peter’s had. I’d personally like to see him have a crush on Olivia Holt’s Tandy Bowen for a movie.
Also, the Russos killed off Black Widow in Endgame. It wasn’t ScarJo’s decision, it was Marvel’s. This is evident in the fact that development for Nat’s solo movie began two years prior. They’ve already set a precedent for killing off major actresses at the peak of their popularity. Surely it’s not inconceivable that they just take a break from another for one movie when there’s so much else that they can cover in the meantime?
