Reimagine the later almost-all-fighting episodes of Dragonball Z, with
Japanese gothic style animation, a bishounen hero and anti-hero, some
Clamp-style women with impossibly long hair, and a tragic story-line,
with lots of destruction of modern Tokyo thrown in, and you have X (the movie).
Lots of gore, with even gorier dream sequences thrown in for good (or bad) measure. Not one for the kids.
A rent don't buy, and only rent it if you're in the odd sort of mood I was in when I picked it up: you
specifically want something with gothic style animation, and only want a feature-length movie.
