Never read the graphic novel and not usually a fan of anime, but this was great. I love that they gave us an unassuming female super hero who was a total badass. Also, the "Bourne Identity" sort of slow reveal of who she really is, and the kung fu choreography was great.
Only disappointment for me is that I didn't know the end would be so open ended. It was like a happier version of the end of Infinity War. Obvious part 1 of a multipart series, which is fine, but I'd feel a lot better about this if they were already filming the next one.
