Story (8/10): There is not much happening in terms of action and crazy plot-twists, since the show is rather philosophic, discussing the eternal questions of "what is the meaning of life" and "what is death".
Art (10/10): The architecture, interior design and characters all look great. If you like jelly fish, chandeliers, cigarettes, fancy wallpapers, skulls and funky hair styles, you've found the right anime. The animation is also smooth enough for the rhythm of the show.
Sound (10/10): It has little songs to offer, but they are truly qualitative. You'll listen to the soundtrack on your free time.
Character (9/10): The main characters are fascinating and deep, but the episodic ones are rather rushed.
Overall: 9/10 Beautiful and not as depressing as it sounds, worth watching.
