The idiosyncratic references to past philosophers -- Nietzsche, Goethe, Descartes -- was generally superficial and would be considered 'fluff' by most people's standards. Surely, though, the brazen approach is worthy of some praise...it certainly made me bust a gut.
Overall, 'Battle Angel Alita' was exhilarating. The characters, obviously, were run-of-the-mill archetypes with little-to-no nuance, but I wasn't expecting much from the outset. While the ending was satisfactory and provided logical explanations for everything that happened previously, it did leave me wanting more in terms of existential themes and whatnot. It felt like they teased our expectations just enough for a grander explanation to come to the fore, but it never materialized. Not surprising...but still.
