While the storyline is a little short in that it seems like just a bunch of random stories thrown together, the themes remain the same throughout the anime and have a good conclusion to them.
It is not only action-wise intense but it poses questions of morality and who is right or wrong in the world, and more importantly which side should you be on.
Throughout the anime there is this central conflict, of making choices and determining if they are the right/just ones, with the main character and the ending is satisfying in learning what his final decision is!
The most powerful episodes to me were 13-15,(the twin-arc), which really touchs base with how messed up this world can be!
