This (relatively) recent repackage is really just the first seven or so issues of the post-Crisis GLC on Earth. It’s kinda John Stewart’s show, though Hal is there (and there are cutaways to Guy on Malthus) though the bulk of the stories have to do with. . . Ch’p! And his evil foe Dr. Ub’x (who has many alter egos, including Truk – a truck.)
It’s very silly and perhaps even childish. . .until Arisia goes through the puberty machine and puts the moves on Hal. Should DC put out a volume 4 I’ll definitely pick it up – not so sure I’ll be chasing down the single issues. (I say this now. . . .)
