When comics moved from mainstream retail outlets to specialty stores in the 80's, they lost a lot of readers. Although comic prices have been rising at roughly double the rate of inflation over the years, DC and Marvel still need to sell something like 18,000 copies of each issue to maintain basic economies of scale. For over 20 years now, the preferred method of generating those sales figures is the crossover event.
If crossover events are necessary, it would be nice if they were good, too. While I think that they tend to be bad, I am always hopeful, and apparently many other fans feel the same way, judging by the strong sales and the negative remarks online afterwards. Even if upper management at DC and Marvel didn't care about the quality of the crossovers, it seems reasonable to expect the writers to care.
Is it possible that crossovers are inherently bad? Maybe the sheer effort of coordinating so many creative people to get their stories in synch with the overall story arc is too much to expect, especially with monthly deadlines on the mainstream titles. Maybe the introduction of an invasive meta-story is too disruptive to the creativity of the typical artist-writer team on any given comic. Or maybe the scale of the stories that a crossover requires tend to limit the writers to a few themes that have been overused by now.
Agree? Disagree? Which crossovers did you like and why? Which crossovers did you dislike and why?
