>>98953088The most well known run now days is the Alan Moore run which is in the middle of vol2.
The story does pick up where the last writer left off, bit it's all quickly resolved cause Moore wanted to get to his ideas.
You could backtrack before Moore's run for the original run or the vol2 stories before him.
They're not amazing but they're readable/enjoyable; especially the Phantom Stranger stories in my opinion.
The n52 run you CAN pickup and read. It has slight continuity cause it continued where the old52's Brightest Day event left off of Alec Holland being brought back to life.
So the best places to start would be the beginning of it all, the best run with Moore, or the recent run of N52. Those 3 would be your best bets.
ALSO if you decide to start with the story runs before Moore, and enjoy them, there is a bigass omnibus that came out last year with all that bronze age goodness in a single fatass book.
