You mentioned Alita, and my face immediately scrunched up in disappointment as I remembered that movie. I guess that accurately portrays how I feel about that film.I'll give it a chance. They're clearly doing their own thing. I can see why they don't want to just do a straight up one to one adaption. And giving how infamous Bebop is at this point, I don't blame them and I completely understand. For right now and still, Alita is still the best live action adaption of an anime.
With that said, you probably aren't wrong about it being the best. Im not particularly fond of Alita, but it certainly isn't Dragon Ball: Evolution, or The Last Airbender, so it isn't exactly a high bar to clear to clear to be considered one of the better adaptions.
Adaptions are always sticky, though. If they try to retell the story as closely to the source material as possible, they get ridiculed for being pointless. Whereas if they try to do their own thing, or they miss a single original plot point, they get ridiculed for not being respectful of the source material, or just using the name for views. They really can't win.
Personally, I just try to see adaptions as something new, and view them from that lens. In the case of this show, I don't care if this is faithful to the original or not. This just looks like the most energetic show that I have seen in years, and I am excited for that.
