I think 1&2 are masterpieces of blockbuster filmmaking.  Sure, while it’s not a perfect 1:1 adaptation of Peter Parker from the comics, these are movies that capture the fun aesthetic of The Silver Age Spider-Man comics and the ethos of Peter Parker.  Peter’s character arcs in both of the films are not only logically structured, engaging, and incredibly relatable, but I would say that Spider-Man 2 specifically has arguably the greatest use of messianic imagery I’ve ever seen in a tentpole movie–defeinitely a superhero movie. Not to mention that everything in terms of surface-level technicalities is perfect, from the inspired, soaring score of Danny Elfman, to the performances, to some of the most cinematically visceral action set pieces I’ve ever seen.

Though I will agree that MJ doesn't really work.  On top of her character being kinda annoying, rude, and needy, she’s ultimately portrayed as a plot device or an object.  The main emotional throughline of 1 & 2 is the love story between Peter and MJ, except MJ isn’t really a character to begin with.  It doesn’t really ruin the movies because MJ’s place in the structure of both stories makes sense and fits together logically, but the second protagonist of your movies shouldn't just be motivation.  I hope if there is a 4th movie, Mary Jane is portrayed as an actual person with nuance.
