Well... I only have seen the OVA - but even in it, there is not just "one thematic thread" and because of that everyone can see it as a "XYZ film" - so if you want "female empowerment" sure, that was not really my take, but okay. If you want the conflict between Human, cyborg and the variant degrees of "human" or "machine" okay... if you want a story about death, disgardment, revival and finding who you are... okay... a story about the slum and discarded of the world fighting to be better and leave the have-not world for the haves... okay (as imo that's the large overall world plot, and the others are plots of how the main character is interacting with all the other characters etc.)
