other than that comic and Kraven's Last Hunt there's not been well-written marriage stuff in any Spidey comic (havent read Ultimate)
Disagree, there's a ton of great stories with the marriage.
- Even before they were married, you had Len Wein's run (ASM 151 - 180), which was the first time Peter and MJ were an actual romantic couple. Wein wrote them as a healthy, mostly normal relationship. His stories lean a bit too far into the Silver Age goofiness but they were still good, especially the second half of his run.
- Gerry Conway's concurrent Spectacular and Web runs (Spec 137 - 172 & Web 47 - 70) are some of my favorite Spider-Man comics and take place during the marriage, featuring it heavily.
- J.M. DeMatteis' Spectacular run (Spec 178 - 203).
- David Michelinie's first few years on Amazing after the marriage are good, though he clearly runs out of steam and ideas in the last few years, probably because he was writing Spider-Man for nearly a decade.
- The two-ish years between the end of the Clone Saga and the start of New Chapter are terrific and probably the last best era of Spider-Man comics. Had stuff like Identity Crisis, wherein due to Spider-Man being a wanted criminal with a giant bounty on his head, Peter decides to forgo the Spider-Man identity for a while with MJ helping him to create four new superhero identities.
- I liked J. Michael Straczynski's stuff up until Civil War.
- Peter David's Friendly Neighborhood Spider-Man is good, though suffers from having to tie into Civil War and other dumb shit at the time. Speaking of PAD, he also got a few good stories in Spectacular after the marriage before he got kicked off the title.
- Then there's the already mentioned Spider-Girl, which ran for over 120 issues altogether. Also, he didn't stop being Spider-Man after losing his leg. Reed Richards made him an advanced prosthetic and he continued on as Spider-Man for a while. I can't remember if there is a big event that gets him to stop or if he just naturally winds down due the demands of being a father.
Peter in a healthy relationship can work. You just need writers who don't suck and don't want to turn Peter Parker into their man child self-insert so they can vicariously bang Black Cat and other superheroines.
