It still frustrates me that (IMO) the three best GLs (Hal, John and Kyle) supposedly won’t be a part of this show so that WB can save them for a movie that might never happen. I like Guy and Alan, but I prefer them to be side characters. Guy is good in the “brutish lout” role, mucking things up a bit but ultimately helping out the central heroes. And Alan suits the “wise mentor” role. That said, I haven’t read any comics with the newer version of Alan and it does appeal to me that a major superhero TV series will have some LGBTQ representation.
But I just feel it’s a mistake leaving your “big three” on the bench like this. And then writing in your own Cole Young character to make it feel even more separate from the original continuity. I’ve seen some of Guggenheim’s and Berlanti’s original character work in the Arrowverse and at least in the case of Firestorm, it sucked. Especially when you have Jessica Cruz right there to be used if you want to center the show on a female GL. Creating an all-new lead just makes no sense to me.
