This series was so immensely pleasurable to watch. It's a horrific and slightly sadistic series that leaves you constantly guessing what's really going on in this small haunting rural village. I must admit though that I couldn't bring myself to complete it. Not because I was scared or anything, but because the explanations for why things were happening were unfolding and I didn't like it. I was hooked on the series from the beginning to around the last few episodes simply because I never really knew why things were happening the way they were. I was blissfully confused and baffled throughout the whole series, and the final episodes were like getting smacked upside the head with the facts of all the episodes previously. From what I've read though, those final episodes didn't explain everything all the way anyway, so maybe its worth watching. For me personally though, I felt that explaining the mysteries of the village the series takes place in took away from the overall appeal. If you love mysteries and creepy moe characters and can handle some gore, I highly recommend that you at least watch the first few episodes. If you aren't completely hooked then I'd say leave the series alone and watch something you'd find more fulfilling.
Oh and by the way, for those comparing to Elfen Lied, this series is tens times better and creepier as opposed to being composed of pure gore.
