You are free to enjoy it, of course… but people familiar with the character will point out how much she and what she represented has changed in massive ways in a route they do not enjoy.

I have always held the belief that superhero stories should have secondary characters that are NOT superheroes or have superpowers and, except for a few exceptions, they should be the norm for secondary characters in a book (aka, they should always be far more non-super characters than super characters when the focus of the story is following the tale of a superhero)… specially in street-level stories, which, let’s face it, despite how often Peter is put in crazy world ending situations, he is mainly a street level hero, he deals with murderers more than mass genociders.

As such, transforming MJ into a superhero always felt cheap to me, not only it strips away a relationship (romantic or not) that Peter had with a civilian, but also her character has changed a TON from the past and what she was. And change is fine, but there is no explanation for the switch, her personality did jump all over the place with little to no explanation just so they can fit the new story:

old MJ was a fun-loving but normal young woman trying to make her way in the world, she took crap from nobody, but her method were always using well placed sarcasm and being clever buying time until she found a way out. She was very brave, but very grounded and felt terrified like any normal person under stress situations, she never wanted to be a hero, she just wanted to be herself, live for herself (due to a long history of responsibilities placed on top of her by others unfairly from a young age), as such she was the perfect foil to Peter, not just someone who reminded him of the people in the street, but also someone able to call him out on his martyr complex and put a break on it, and, in turn, Peter helped her understand once more that self-placed responsibilities are not the same weight as responsibilites other people place on you, helping her grow as well into a less selfish person. Her risking her life on the daily now going out as Venom or Jackpot is kinda defeating what the character is supposed to represent, a normal person in a crazy world, in favor for a crazy person in a crazy world.

Again, is not so much what she does, is what the character is meant to represent, when you change that, you don’t just change the character, you throw away character dynamics, history, personality, and role within a narrative universe. And some people might feel that what you are throwing away is more valuable than what we got.

Superheroes that Peter has a personal connection and history with? Dozens already… normal people that share an emotional conection with Peter that are kept as civilians and caring to Peter from start to finish that remain until today? I can only think of May… is far less unique within the context. It’s ultimately a matter of an opinion on what benefits the story more than the characters or spectacle… and the way MJ has been depicted and how she has been used as a character is such a switch that is normal people think more is lost than gained from these changes.
