Another Madhouse over-acclaimed show that, imho, only deserves a watch for its awesome technical side: top notch OST, uncanny lighting, very fluid and detailed animation, outstanding directing and much more.
Of course and still imho, if you are looking for a rock hard story with thing like coherency and a well developed character psychology, I wish you good luck searching elsewhere...
