Giffen started the series and it was, honestly, luke warm. Then Rogers took over, shortly after, (Trade 2 or 3). And suddenly it was heading into OMG Great Land, though you didn't really notice. You just started noticing all these awesome moments (I mean Jaime's mom, threatening Guy Gardner..and winning. Awesome)
And then it's all wrapped up with BB 25 which..was rather sad. Awesome awesome arc. But...That was it for Rogers, and the series never got as awesome again, and it went to cancel-land.
So Get the trades. 1 if you want. 2 up through whichever trade has issue 25. Then stop. It's for the best.
