There is no downside to Sony and Marvel agreeing to work together for mutual benefit, artistically or financially.
Other than the fact that currently Marvel seems to have no freaking clue how to write Peter Parker.
I haven't read the comics for decades. I couldn't give a stuff about them.
This is the MCU, it's a whole different ballgame. They'd use Spiderman well.
So becuase the animation division makes a mediocre version of the character, and the comics can't write the character worth a crap these days I'm supposed to have faith in the movie division for reasons.
Especially when the story potentially used to bring him over was one where he did something unbelievably stupid that was cosmically erased in a crappy story, makes no sense in the context since Stark talked him into it and after Iron Man 3 he would have to be an idiot to do so this time, and has NOTHING to do with Captain America: Civil War's plot becuase this version isn't about secret identities.
They might even inspire Sony to do so in their next outing...
Meh, all they have to do is stop trying to make the next MCU and they're good.
