This anime can be enjoyed by a wide variety of people. If you are fascinated by the Japanese symbolism or like the thrill of tense moments or enjoy common people finding themselves challenged by supernatural mysteries this one is for you.
The dialogs are very clever, the visual elements are stunning and the plot is definitely interesting. There is just one problem, but admittedly it is a big one: It is very monotone.
The same scenario and conversations are repeating themselves every episode over and over, so if that is something that annoys you, you might want to stay away from it, however if you can get through the first 6-8 episodes, you will be pleasantly surprised as the ending is worth waiting for.
If not for the repetitions i'd probably give it an 8 or 9.
