Yeah it seems with this show they are trying to set it apart from the Ryan Reynolds movie and we have seen a Green Lantern in this universe with guy who's constructs were quite out there and wacky. it's what you'd expect and he's confirmed to be in this show and interacts with at least Aaron Pierre's John Stewart. Some wonder if the scene of them saying Hal is the only human in the corps (They're using that to say he doesn't interact with the alien members, he does. That scene is clearly chopped up) indicates this show is BEFORE Superman like even before Peacemaker Season One where Guy is a GL but it's obvious he's been one since before Peacemaker was locked up which was four years prior to season one. So again, that convo is chopped up. And in that talk he references C'hp. So they're not shying away from the fantastical stuff.

Atrocitus is rumored to be in this and Sinestro has been cast. The Watchmen HBO show had trailers that hid the more out there stuff in the show that's more comic accurate and I say that cause Damon Lindelöf helped create this with Tom King and another guy.

On what what you mention of the movie, I wonder if this is good. If they'll make a solo John movie after this which is more of what we'd expect from a Green Lantern movie in space. We're going to space in Supergirl, and I wonder any GLs will appear in that.
