This anime is originated from Sunrise Studio which you know is famous for the hit series Cowboy Bebop back in the day. I myself found it very interesting and well-crafted. Its visual and soundtrack are out of this world just because of the realism. The characters and the main story line is also built up very well. One of the downside of it for me personally is the female character. I do not think that someone in reality would be that easy to persuade and all that. Another thing is the ending song:)))) It just did not work for me as good as the OP. But overall, I think that this one is definitely worth your time.
