Booster Gold is an upcoming superhero comedy television series, based on the DC Comics superhero of the same name. It will be an installment of Chapter One: Gods and Monsters in the DCU. The series is produced by DC Studios and will be released on HBO Max. According to James Gunn in the original DC Studios announcement video for Chapter 1 of the DCU…
“Booster Gold is one of comics' really popular cult heroes, he's a fascinating guy, he's a loser from the future who uses future technology to come back to present day and become a superhero so that people will love him. It is basically a superhero story of impostor syndrome in an HBO Max series.”
BTW, I got the Synopsis and the Quote from the DC Universe Wiki.
