Then this is the perfect anime for you, friend.
In all seriousness, this one is pretty heavy. Lots of graphic violence, disturbing scenes, non-explicit sex scenes; it's quite the ride. The action is somewhat hard to follow at first, but there's a clear plot and the main characters are well-written. The story and main character are extremely interesting, and Angelo is such an intriguing specimen who hooked my attention from the very start and kept a firm grip until the end.
It also had a very good ending in my opinion, but as with every ending, I doubt everyone will be happy with it. However, it was wrapped up nicely and had a heavy melancholy feel to it which was very fitting for the theme of the show.
