At first, I really found it interesting and wanted to know more, but when it finally came to the point where they tell you what's going on, it doesn't make sense anymore( actually most of the anime doesn't lol ). They all start making stupid decisions and going crazy. It's a fast way to end the series, but a boring one in my opinion. The soundtrack was okay, it did make me have that scary feeling, but not memorable. Most of the characters were boring or really unlikable, not because of their personality, but because they didn't even have one! Especially the main character. He was just there to make the story go further by asking questions and that's it.
