Well it is as the name suggests is on much darker side of the world. It has drugs, money, prostitution, blood and gore. For me being the fan of seinen genre the story was pretty good but the only problem i think this show had was that the only good part of the story was in the second half as we explore the characters back stories. For me the biggest disappointment was the ending of the season as it didn't had any conclusion and they just ended it on cliffhanger and i don't particularly like these kind of shows. Well for the most part the story was pretty well done and i really enjoyed it,
Now for the animation and sound the animation for this show was done by Manglobe which was pretty decent enough as the most setting was in a town with cramped streets. For the sound it was pretty good as it had a electronic mix to it which i pretty much liked.
Now for the most part i think it was pretty good but i don't recommend it watching until the second season comes out.
