the concept of the show is amazing and original. the animation is attractive, and the story plays out its mystery well.
BUT the plot twists, as thrilling as they are, are TOLD to us in long monologues and dialogues, making it hard to keep up sometimes (because i watched the subbed version).
This dulled the effect of the plot twists, because often we'd just be looking at still images of a bunch of people jumping to conclusions that were unrealistically made or hadn't been actually shown to us. It doesn't let us try and fit the puzzle pieces together.
but its a good watch. Its not bad at all. Just not totally captivating for me.
