In spite of it's rating, this is my favorite anime of all time. Horror is a genre that does not generally fare well among anime fans, however this gem remains hidden by its poor ratings. This show excels at its character development. By the end of the show, the characters have all been thoroughly explored and we get to see that many of them are fighting to survive for more than just their own sake and many of them are willing to sacrifice themselves to save their friends. Honestly not sure why this one got such a bad score from others. It goes up there with Higurashi asa show that is crushing but amazing at the same time.
