The biggest strength of this issue is that it stands on its own. That is a hard accomplishment for any one-shot that is related to a mini-series or event book. There is just enough detail supplied to tell you what is going on ( information learned more extensively from the main series ) without feeling left in the dark or having a “wtf is going on” reaction. My critique would the ending, which is by design not a solid, closed conclusion. It is meant to bridge back into the main title to finish out the adventure.
