I'm an unapologetic fan of Booster Gold. When he's at his best, he's an incredibly powerful character that can hold his own against Superman-level villains that has an incredibly heroic heart buried under layers of bravado and self doubt that you usually just don't see in DC. If he were a Marvel character, He'd be a front runner for the Avengers.
Unfortunately, Booster was a victim of Keith Giffen & J. M. DeMatteis's Justice League. It was a great book that infused lots of humor into the world of the Justice League, but Booster was used as little more than an ongoing punchline, and he's never really recovered. Geoff Johns went to great lengths to resolve this, but his concept was rooted heavily in time travel, which is a fundamentally flawed idea in an ongoing medium like comics, and something we're deliberately avoiding. The single act of time travel that's intrinsic to his story can be explained away with the involvement of Rip Hunter, the DC universe's Doctor Who allegory, but we really don't want to push is.
The important thing with Booster is to allow him to be a hero without compromising the layers of self interest and doubt that make him such an interesting character. To this end, I crafted his timeline to give him important rolls to play within the Justice League. We can understand that within that story, he can still occasionally come across as a fool, so long as he continues to also be the hero we know he can be.
