As a comic fan, I am very pro-married Peter Parker, though for the moment I am hardpressed to recall stories whereas their marriage was featured in a great way. Ever since OMD we've been shouting we want it overturned (despite his post, I still want it overturned too).
But I wonder - what were good stories written where their marriage was intact?
Stories to come to mind are Harry Osborn's Spectacular Spider-Man - the trio created real tension, Erik Larsen's run on Spider-Man had a good subplot. I cannot think of that many. Do you have others you can add?
