Wasn't the "Truth" intent to be that each book would cover a piece of puzzle, so "Before Truth" happened, then Action happened, then Batman/Superman happened, then Superman/Wonder Woman happened, and now we've swung back around? I'm not sure if everything falls perfectly into little four-five issue chunks yet.
I read this for the Porter art, honestly. I'll support that guy forever. The art was aces here. I thought the story was okay-ish. Certainly the mythbrawl concept alone is quite fun.
