Thinking about the way BND uses MJ and the way Spidey 5 is likely to use MJ sent me down a bit of a rabbit hole, and I think I've put my finger on why the MCU Spider-Man feels so offputting.
Basically, what it comes down to is that the MCU Spider-Man movies don't really know what to do with Peter's supporting cast or personal life or... Or the very concept of Peter Parker as a human person outside of being Spider-Man.
Homecoming was probably the most Peter Parker that an MCU film has featured on account of its mission statement of keeping Peter grounded.
But then Far From Home took him away from his setting and supporting cast to send Spider-Man globetrotting with S.H.I.E.L.D. and Mysterio. It still found excuses to bring his class along with him, though, so he could get into Peter-like shenanigans in these strange locales and start a relationship with MJ.
Nonetheless, May and Ned were reduced to recurring gags.
And then No Way Home pretty much kicked Peter to the curb. From the moment Doc Ock arrives on the film, it is 100% a Spider-Man movie. MJ and Ned are paired up to wander around being Spider-Man's sidekicks for a bit, May's killed off, and ultimately the very concept of Peter Parker is deleted from the universe.
Which then brings us to BND, whose central thesis is that Peter Parker is an integral part of who Spider-Man is and that Spidey needs to be feeding his Peterness too. It reconnects Peter with MJ and Ned, and ends with the promise of a restoration of Peter's identity outside of work.
What does that even look like? Who even is Peter Parker at this point?
Peter has no day job. He never went to college. He's apparently independently wealthy enough to afford multiple years of housing and supercomputers and shit without an income; No idea where that money came from.
He doesn't have Aunt May. He doesn't have the Daily Bugle or Horizon Labs or anything. He doesn't have Midtown High anymore. He's never really been established to have any sort of dreams or aspirations besides "be Spider-Man" or alternatively "get that cute girl to be my girlfriend".
Flash sometimes exists for like one or two scenes of a movie.
It feels like we started Homecoming with a notional idea of Peter Parker and then spent the next three films subtracting elements from him. What is there left to build from?
If the idea at the end of BND is that Peter's going to take more time to be Peter then Spider-Man 5 is going to have its work cut out for it figuring out who Peter Parker even is. Who he can even be in the corner he's been written into.
But I have a sneaking suspicion that a lot of the Peter elements of Spider-Man 5 are just going to be spent on "get that cute girl to be my girlfriend", since they left that "MJ has a boyfriend now" plot thread dangling. Maybe it'll be about rekindling his relationship with MJ. Or maybe Black Cat will be in it and it'll be about how she's all wrong for him and then it'll be about rekindling his relationship with MJ.
I do not buy for one second that the MCU actually intends to leave Peter and MJ split up. I thought before BND that we were going to have to spend a movie painstakingly watching them get back together, and now I've increased that estimation to two movies of painstaking Will They/Won't They shipping of a couple that already did and it was already fine before they fucked with it.
I hope it's not just Ned and MJ. Because Peter needs, like, an actual life. Even if he's going to have to build it from scratch because the films have burned all of his bridges to the iconic Peter Parker stuff.
Please let the big Spider-Man plot of movie 5 be in service to Peter's growth and development as a person rather than just having Peter be what Spider-Man does in his downtime. Peter needs another Spider-Man Homecoming to detox from the No Way Home/Brand New Day double-whammy.
