I actually think the comics would be worse. Not because Peter should be single, but because so many writers don't know how to write a marriage or even an relationship in which the love interest isn't some prize in the end. All these writers seem to be burdened by the marriage. Marvel has spent so many years trying to get rid of the marriage, which resulted in a bunch of sucking arcs, that I feel OMD was for the best because it allowed for the writers to just go forward. However, I do think Peter will eventually get back with MJ. There's a reason why her character has existed for so long, while Gwen Stacy was killed after a few years (Gwen sucks and was boring/poorly written). I don't think Peter is going to be marrying some other women anytime soon seeing as this was the reason for the retcon, so I'm sure he'll get back w/MJ. In the end, it will probably all work out for the best because we'll have a good writer and the relationship will be back--at least I hope this is what happens.
