Let's face it: The Batman line from DC is in big trouble. There are currently 10 separate ongoing titles, not to mention mini series, one-shots, etc., and none of them are selling what they should be. The current mega-crossover, "War Games," is a creative disaster, and the only title with any real critical buzz is Gotham Central, the lowest selling title of the bunch. For a flagship character, Batman deserves better.
So, for your consideration, here is how I'd redesign the Batman line for maximum sales and creative worth:
The line should be cut down to four titles. There are four weeks in a month, thus one title each week. Those titles should be: Batman, Detective Comics, Batman and Robin, and Batman Family. Here's how I would break down each title:
Batman: This is the flagship title, the place for big-time writers and big-time artists to come in and tell big-time stories. Stories of four to six issues, unburdoned by a strict adherance to continuity, which can then be collected into trades and repurposed in the broader market. Everybody's got at least one Batman story in them to tell, and every super-hero artist wants to draw Batman at some point. This is the book that all creators should be crawling over each other to do.
Detective Comics: Is the other flagship title, but should take a different track from Batman. The empasis in Detective should be on detecting: mysteries, crime thrillers, etc. Instead of hiring regular comics scribes to write the series, go after the top names in thriller and mystery novels: Dennis Lehane, Margaret Collin, Sue Grafton, Carl Hiaasen, Anne Perry, Patricia Cornwell, Robert Parker, James Patterson, etc. Not only would there be great PR opportunities, and not only would DC be tapping into the existing fan bases of these authors, but we're also likely to get some damn fine stories. Yeah, most of these authors would be 'slumming' in the poor-paying world of comics authorship, but I bet a lot of them would be willing to give it a go for a chance to write a Batman comic. For art, this title should feature artists who, while not surface flashy and 'fan-favorite,' are excellent storytellers, like Michael Lark, Steve Lieber, Javier Pulido, Steve Dillon, and David Lloyd.
Batman and Robin: This would be the 'in-continuity' Bat-title, featuring Batman and Robin in continuing stories, facing off against costumed villains and occasionally interacting with the rest of the DCU. It should have a regular writer and artist team that are capable of turning in exciting and on-time work. This would be the title for those readers who want their Batman to be a super-hero.
Batman Family: Finally, we ressurect the old anthology Bat-title. It should be at least 80-pages, if not 100-pages or more, and come out every month--for no more than $5. Four or five stories per issue, a combination of one-offs and continuing serials. This would incorporate all the other current titles focussing on secondary characters, such as Birds of Prey, Gotham Central, Robin, Batgirl, etc. Yeah yeah, anthology titles don't work, but with the right mix of characters and the right price point, this can work. Plus, the features can be stripped away and assembled into manga-style paperbacks and racked alongside their bretheren from across the Pacific.
One thing you'll notice from this rearrangement is that there's no room for mega-crossovers. This is good. Such events may lead to short-term sales bumps on the lower-performing titles, but in the long run they do more harm than good. With the line-up as I've outlined it above, each title is an event unto itself.
So anyway, those are my thoughts. While I sincerely doubt that DC will be interested in going this route, they're welcome to take it and work with it if they so desire.
