I thought this anime was brilliant. It was very entertaining and each episode had a moral philosophical meaning embedded within it. I found the story very profound and the overall message that if we as human beings do not operate out of love we will succumb to our desires. If we stop using our hearts and allow our worldly desires to consume us, we become the very same monsters that we detest.
Overall, it is a short entertaining anime series with a fair amount of wisdom contained within it. I definitely recommend watching it and hope there is a second series. I almost did not watch it because when I checked the reviews they were fairly low. It was good enough to warrant me making an IMDB account in order to provide it with a more respectable rating.
