I remember sitting in a horror anime panel and watching clips from Berserk: The Golden Age Arc. I wanted to see how truly horrifying Berserk the anime was. After watching this anime, I can clearly say this is not designed for children and it should be rated Mature. This is Not Safe For Work. If you choose to watch these films, do not watch around people or in a public setting.
Movie Synopsis: Jonathan Shannon (Ryan Phillippe) gives his 17-year-old daughter Clare (Joey King) an old music box that promises to grant its owner seven wishes. Skeptical at first, Clare becomes seduced by its dark powers when her life starts to radically improve with each wish. Everything seems perfect until she realizes that every wish she makes causes the people who are closest to her to die in violent and elaborate ways.
Another is an anime based on a Manga and Novel written by Yukito Ayatsuji. This anime will screw with your head from beginning to end, trying to figure out why all of this is occurring. There is a lot of violence and gore which I do not recommend for the light-hearted. This is a good horror series. It will shock you when you least expect it. This story takes many turns and there are lots of plot twists that will leave you baffled.
