What can I say? This was a very interesting anime, but many people may not be able to stomach the reality of what this anime represents. Too many people are put off by this because of its brutality but this is what human nature can and sometimes becomes. The anime is vile because humans can be vile we all have the potential to become monsters if the right circumstances are met. If you can understand that is what makes us human then you should be able to enjoy this anime.
