What can I say? Good stories are good stories, and good comics are good comics. I'm guessing that it was Treiman's art that caught my attention and made me want to give this series a chance. That's probably true for the most part whenever I pick up a first issue of a new series. I care about the writing too, but it's harder to get a sense of that when you're just flipping through a book at the store. With that said, it's the story that's keeping me coming back for more, and it's also the reason why the latest issue was near the top of my stack when I sat down to read today's new releases. (They're up to issue four of six, by the way. If you can't get a hold of the back issues, I'm sure that a collected edition will soon follow when the entire series is released.)
What's also great about this series is that even though my head is cluttered with various characters, stories, and plotlines, I feel like I can easily get back into the swing of things with each issue. Pretty much every issue is self-contained, and I imagine that if you picked up the third issue, you'd be able to follow along just fine and not feel too lost. While I'm sure that this series will reward me even further when I sit down to read all of the issues in one sitting (which I very much plan to do) it's nice to be able to enjoy what's going on without having a very good recall.
Perhaps I'm going too far, but I'd put the sense of timing and the fluidity of perceived motion up there with the likes of Bill Watterson (Calvin and Hobbes) and Carl Barks (Uncle Scrooge). I'm not sure whether John Allison describes in detail exactly how he wants everything laid out or whether Lissa Treiman makes those decisions, but either way it captures that special something that only can be done in comics.
I don't know what's next for this particular pair of creators. I wouldn't mind seeing more Giant Days. I also would be interested to see what else they can do, either together or apart.
