I (very recently) just revisited the Geoff Johns run. From Rebirth-New 52. He really did something special throughout his entire GL run. I know some say the quality dipped after Blackest Night, but I was still having a blast reading past that. Then the other series like Red Lanterns, New Guardians, GL Corp, the solo Sinestro series... I've pretty much enjoyed everything around that era. I just hope DC isn't shy about using Johns material. He was involved with the show at one time, but it seems he may not be involved at all at this point.
