Similar to Korean movies like Kim Ki Duk's 'Adress Unknown' or 'The Coast Guard' with that haunting atmosphere, creating a desolated and cold world that seems to be forgotten and away of god's glance, suspictions and plots between police, miltary forces, spies, etc. Also with the dehumanization of those who are suposed to protect the civilians.
It has a great animation, music, and interesting things as its pace and how it relates the story with the little red riding hood tale. But in the end it doesn't achieve to explore to the best all the subjects and story it raised.
