A very dark and obscure story that does catch your attention throughout and draws you into the series. A lack of information given to you throughout the series is what keeps you interested in the story and what will keep you watching.

That is, until roughly the last few episodes where the plot and progress of the story does take a bit of a dive and I found myself being disappointed by how things suddenly transpired. The ending feels rushed compared to how the plot had progressed and it doesn't quite fit well with how the story had progressed so far up to that point.

A few words of warning. DO NOT watch the OVA before the series, it will give away some important details.
One other major negative is the music, I think they could have done better on that.

But overall, a very good anime and I would definitely recommend it to everyone who likes dark, thriller type stories. (show less)

After now having seen the entire thing, I gotta say its no suprise why this anime is so popular. Its very well written. Its full of suspense, and eerie and/or scary moments including the various death scenes(which are awfully creative), but also the character interactions, and how the mystery is built. I was trying to keep track of the death toll, but I lost count around halfway through the series(that ought to give you an idea of what´s in store). Also one word of warning:this anime is not for the squeamish. The death scenes are quite brutal, and there can be quite some blood splatter(sometimes there is less blood, but they use it so effectively, its still scary). It´s not the most gorey I have ever seen, but it was still enough to be schocking and scary, and I guess that was the point, so kudos to the shows creators :) (show less)
