Query: what a big let down

This anime was one of the biggest let downs I watched in a long time! The idea is great, characters, and the stile are all good. The problem is every 6 episodes the stories starts over form the beginning. Each version has little to nothing to do with the one before it. There a completely different reason for the murders and a different killer. This series could have been a really good dark scary series. Instead it just frustrates you to the point of not even wanting to finish it. Unless you get it for free don't waist your time!
