Honestly, JLA has always been a rather schizophrenic title. Since the 80s, it's had ebbs and flows of quality. The Detroit Era wallowed in inconsequence, then COIE, and the Giffen/DeMatteis League, which had years of good stuff before it just couldn't contain itself, and then the League limped on until Morrison revitalized it, and then it started falling apart again just before Infinite Crisis, and apart from Johns' part of the Lightning Saga, it hadn't been readable until McDuffie took over. His has been hit or miss, but hopefully this has just been the beginning of the flow rather than another ebb . . .
