Major bad vibes.

They are reducing the budget and a Green Lantern show needs that as much as the viewers need air.

Guy could've been incredibly fun as a new recruit, but Kyle would've made more sense in that role with Hal being the veteran Lantern.

Alan being openly gay is just a recent thing and it's the least interesting thing the character has going on in his entire publication history.

Starting with John is short-sighted, you either gotta build to his introduction as a recruit or introduce him as a veteran lantern already who is equal to Hal and Sinestro.
