Personally I would say the anime was beautiful. It felt so damn tranquil. Yeah I have seen many reviews saying that the story wasn't so good because the title suggests something else. Well supposedly it suggests psychic battles. Is it? If you are looking for action I recommend not watching it but if you are a lover of beautiful things its a must watch. Yeah at some parts its quite hard to understand but the ending puts all things to places. The ending? Makes you sad really sad until the ending song ends. There is always something good after that. A typical happy ending itis ^^

I hope my review helped :)
