This show was very hard to get through. I had no attachment to the characters and by the end, I couldn't name three adjectives to describe the main character. It felt like I was constantly out of the know and there was no bonding between the characters at all. They did not seem to care about each other and didn't have much humanity.
I value a good storyline in which characters have definitive traits, relationships are made, and there is a clear motive. Many things in this show were left up to interpretation and so I had a hard time following. I recommend only watching the anime. This was a waste of time.
