I loved this anime, it's not perfect, but I don't see why people would be so rude about it. I understand they didn't adapt the most crucial parts of the investigations for most of the murders. Seeing as the two that had the most in depth that I can think of were the second investigation and the first. The fourth was very rushed. Over-all I loved it, I did play the game, but I don't see a problem with the adaptation. If I hadn't known about the anime, I wouldn't have played the game, probably.
