Yeah his stuff was good. Minor point seeing that reminded me, can never make up my mind if I prefer the ring that's just the symbol of the circle with the symbol in it. Certainly not a big deal, neither of them is bad or a super important detial.
So without getting into specific details, it seems like the last issue of GL brought back Hal's outdated costume with the green portion covering his crotch. Naturally I'm hoping this isn't permanent, given the previews for Dark Crisis where Hal still has his post-GL Rebirth outfit, but by the end of the issue they show Jo restoring her original costume with the green shades while Hal stays with the onesie or whatever you want to call it. I've been on record before just how unappealing that looks to me, so I can only hope this won't be the case going forward. Other than that the issue itself wasn't bad and Hal was written well in it. But that costume, man, it's always fascinated me how it's literally the same outfit but when the green covers his crotch makes it look so awful.
Yeah, I can't imagine that they'll keep his silver age look. (or much of anything else introduced in this run) DC keeps wanting to reset the GLC but then has no idea what to do with it once it's reset. Then writers come along and basically just want to start with a clean slate and work with the GLC that they're familiar with, free of the baggage of whatever slight, superficial tweak was made in the previous run.
I wouldn't worry about the costumes, everyone was wearing the "standard issue" to signify the "factory reset" of their powers (rip cosmic grail powers). They could have showed Hal changing into his modern look but it was probably enough to just show Jo doing so.
So as I understand Hal's connection to Cosmic Grail is gone now?
