How do you evaluate the animated movie "The Great Protector"?

"The Great Protector" is a story that surprised me. This surprise stems not only from the bloody violence throughout, but also from the philosophy of human nature presented in the dark colors of the film. The metaphorical totalitarian horror, apart from the regret that the completion of the plot is unsatisfactory, this animation seems to be extremely picky, and it far exceeds my usual understanding of contemporary domestic animation.
