Before you say, because I like Peter alone or I like Peter with other women. I come to the conclusion, the character revolving around romance(on fundamental level of tying a context definition of his whole character on a meta level as a hero) is what kills his appeal for me as a relatable human on more than a social standpoint, I believe Peter Parker should be the totality of human experiences, not just the best of people who represent human shortcomings and progress. Mary Jane Watson is a character that grew the most based off the latter and became mandatory to Peter as a main standard to the stories. MJ to me should be demoted to a main role emphasizing the highlights of Peter's life but she shouldn't be the focus of the story of Peter and his experiences, the story of Peter should be fundamentals about himself and only himself narrating about the good(became a avenger, getting married, made alot of friends, saved millions of people) and the bad(got his uncle shot, got mistrusted by people, people die in his behalf, nearly gets killed and got killed, letting his wife con him in agreeing to sell his marriage to satan) by just going through life a superhero. MJ is a varying part of what makes Peter and the Spider-Man comics great(one of the most popular at best), the character is best when she and other cast members serve to the main character while he moves the plot around which is about him(what ever the plot is). The books and future media shouldn't stick MJ in everything fundamental about Spider-Man, especially not as the main love interest because thats not all relevant to Spidey in context as a superhero plot nor does it have to be the epicenter for soap opera tension and drama(like Spider-Man losing a job, feeling insecure when he has little respect from heroes, and of course the parker luck), it's optional.
I feel Spider-Man needs to define the franchise without the key roles for a change, and go back to being about the experience and changes than the foundations that the character experienced in the past. MJ being his wife is one of those experiences and doesn't really need to stick because it's not Amazing Spider-Man and Mary Jane, it's just Amazing Spider-Man. It doesn't matter whos dating Peter its about keeping the eyes on Peter as a storyhook for anything he experiences, develops and goes through. The only thing that should stick to fundamental default as a experience for Spidey's concept is getting bitten, uncle bens death and being peters motivation, his awkwardness, his funny banter and jokes and many times the determination to do whats right even if it sucks. The marriage and even MJ herself, the girlfriends, the jobs, the suckiness he experiences, the villains he fights outside of the main villains and even the age of his aunt is all subjective variables in the largers scope of things that define Spider-Man itself. To me that is.
Especially the marriage, it's overhyped nostalgia that was never masterpiece work and a overrated experiment that served to let writers self insert being Peter having a hot wife as a nerd. I gave more a damn abut felicia and peter than MJ since him and black cat have more chemistry and stuff in common than a nerd and a tomboy hedonist turn spunky house wife.
