Despite the majority reviews and ratings on this anime calling it "senselessly violent" and "cliched", I'd heavily recommend one to at least watch a few episodes of the anime if you're into psychological/horror themed anime.The majority criticism I've seen has criticized the vary fact that it's meant to be dark and violent and sad unlike your regular happy-go-lucky magical girl type anime, the story and characters are spot on for the genre in my opinion and the story won't leave you disappointed until the end, where the show very blatantly sets itself up for a second season to explore the other elements in the show. Unfortunately, a second season isn't likely due to all the backlash on this anime, again, just for the reason of bringing a dark twist to the magical girl genre which most reviewers don't seem to be able to handle. This anime is not for everyone, especially if you're not the type to enjoy dark stories, but if you are, I cannot recommend this enough.
