It would be easy to dismiss the fifth issue of Heroes in Crisis as a glorified filler issue. It’s very much a middle chapter of a longer story. There isn’t much in the way of plot progression to be had here. The emphasis is more on imagery and mood than story in this issue. But as imagery and mood are pretty much the two major selling points with Heroes in Crisis, that’s really not a bad thing.
The series’ focus remains where it has been these past few issues, with Batman, Superman and Wonder Woman performing damage control after the Sanctuary massacre while Booster and Harley continue their dogged pursuit of the “real” killer. The narrative inches forward in these pages, mainly as Tom King’s script begins teasing the identity of that killer. Still, the end result is far more questions than answers, which may be a hard pill to swallow considering that issue #6 is another flashback chapter.
