I have already done a rating of this anime but I need to change it. I have rewatched season 1 of this show three times now and just think that we need to appreciate how amazing it is. I loved watching this show every single time and it still has me on the edge of my seat even though I know what is going to happen. I recently watched this with two of my friends and they are now obsessed. I love all of the characters, especially Ray and Norman, and the plot was so amazing as well. 

Also, the first episode of season 2 is insane!!! I can't wait for more to come out.

100/10 I highly recommend this one. It's on Netflix and there are only 12 episodes in season 1 so you can finish it in a day or two.
