I don't feel excited hearing Raimi is coming back. I mean he he peaked in the early 2000s and hasn't had a very critically acclaimed directorial life since.
Also the OG spiderman movies feel distinctly unlike the mcu, though it is hard to guess how much of that was raimi's own vision or studio mandates.
As a singular unconnected film, this would be a great choice, but I'm doubtful there won't be any creative conflicts in the production room.
Strange 2 might be a civil war or ultron kind of event, and if so, I see no way for marvel to just hand over the keys without defining the sandbox first.
