This dorama is absolutely amazing. I was hooked from the moment it started to the moment it ended. The story is so tense and so mysterious I had no idea who it would be or what would happen. The acting was out of this world, especially Ichihara Hayato he had at least 3 scenes where I just couldn't look away from him, he was absolutely amazing in this! The others were great too! I like they were all flawed and corrupted characters too pretty much! The music again was absolutely amazing, such good songs, yes they were English but were hella good ones! The soundtrack too was good. A little film studies here but I loved the crispness of the camera shots and the colouring was awesome and the angels were great too! Only down side? I felt the last episode was weak and rushed. Besides that I actually have NO complaints about this dorama! Dying to read the book now too!
