Well, this anime is just perfect! Let's go:
They story is great, one of the best mistery animes i have ever seen, the plot will trap you since start. Awesome plot with much blood. I must say that when i started this anime i was kinda frightenned D:
Characters are unique, crazy girls with lots of blood, at first this anime can confuse you, but then u will catch the story. There are many secrets that you will discover trough the anime. Give this anime a chance cause it will be worth it.
This anime is like a game, and you will be recieving clues in order to catch the assasin.
On the other hand first season of Higurashi isnt as good as second, since in second season you will discover even more.
