Trinity of Sin Pandora #1

Like most multi-title crossovers these days, the first parts are always very confusing. Everyone has a general idea of the myth of Pandora. What DC appears to have done is cross the 2nd version of the Crimson Avenger from the JSA book, given her the looks of one of those Wildstorm characters who's name eludes me right now, and totally screw her over. The Council were total jerks back in the day. But that was the past. In the modern world Pandora's mission is rather muddled. She wants to save mankind from the sins she released but she willing to whack those same people who are under their influence? She's already looked into finding the answer to her curse in the original box but old man Shazam tells her the answer lies there? As a story in itself, it might have been manageable but knowing this is the starting plot point for the upcoming Trinity War, I can't even guess as to how this will all work. So the question becomes how big of a fan are you. Are you willing to read (in depth) through at least five main titles and a couple mini's for the answers?
