I think what will make or break this show is the music. I've heard from a few reviewers on how the music itself is a character and the show is almost dull or average without it. Having owned the DVDs and watched them multiple times, I am inclined to agree. In hollywood there is this trend where directors want the music to be as unintrusive as possible, leading to very subtle and uncompelling musical tracks that are barely recognizable. I'm worried that the adaptation will suffer the same fate and from what I'm seeing so far this might be the case. I can remember almost every song from the anime just from watching the anime alone, if that's a measure of how memorable the soundtrack is as well as Kanno's passion for the artform which is more than I can say for a lot of hollywood movies these days.
I don't mean to jump to conclusions, but if we don't have a great composer then this series will flop. There was more to bebop than just the characters and the setting, the music was literally half the show's charm. That said, Netflix has worked with Japanese studios in the past, so I can't see why they couldn't call up Yoko Kanno and have her get The Seatbelts back together to make another soundtrack for the live action adaptation.
