No, you're not missing anything. You're not out of order. The Bill Mantlo's out of order! The whole frickin' system is out of order! Marvel is out of order! Justice is out of order! The vending machine next to the men's room, that sells candies and coke is out of order!
It wasn't quite that quick.
Volume 2 even has a -1 issue that deals with their marriage, but...
Welcome to my nightmare.
That's pretty much how I feel about not only Mantlo's run, but v2 as well. In fact, all the post-1 volumes (some of them just had more enjoyable strangers than others).
v1 does get better, though (imho). Just, not in a hurry. And it'll never be as good as it was under Byrne.
