Oh my, this is a story to write about. The first thing to address is the art and animation. It's beauty is like a fluttering cherry blossom, swift, clean, and thorough. The story is well thought out, and really fun to get into; however, the one thing i had trouble with (me still being new to anime, so to speak) was the fast pace subtitle to animation: since it's originally made for people that understand the language, it won't slow down for you, which is understandable; therefor, it would be recommended to take the time and learn a bit of the mandarin, Chinese, language.
Another thing to address would be the sound. The flute mixed perfectly into the feel of the dreaded night that the dead rise to take revenge once more.
Im giving this anime such a high rating because it does, indeed, deserve such of a high rating. The art, sound, and overall enjoyment was outstanding, showing what china can do.
