Glen Powell is definitely a top fan casting from a really superficial standpoint, but I think when all is said and done people just want the character to finally be done right. And I've said I have no interest in seeing a gray haired Hal Jordan playing a second fiddle and either having his stories stolen, turned into a bad guy to prop up the "real" main character, or both. The Tomorrowverse did it and that flop speaks for itself.
