‘Convergence’ #0: just plain zero
Convergence #0 occupies a very strange space. DC had a bout of #0 issues a while back, not only an entire month dedicated to them but also a few afterwards such as Harley Quinn #0 and Justice League United #0. The problem with #0 issues in general is that they tend to fall into one of two categories, either a) just the first issue of the actual book or b) pointless prelude material that will only be explained in the #1, making the issue itself nothing less than a cynical money grab. Convergence #0 is the latter.
