The main "protagonist" is one of my favorite characters of all time. In fact, a good chunk of the characters are really well portrayed. They have clear (but often complex) motives and thought processes. They're easy to hate to love, or love to hate. Or love to love, as the case was for me with some of them.
It's an original plotline. If you're into the idea of social justice but don't want something that's full of graphic murder or drawn-out fights, this is the anime for you. All of the fighting is more mental than physical, which is what I really liked. If you're looking for something that will make you constantly wonder "what next?" this is definitely for you.
I still stand my ground that the middle part is drab and almost unnecessary compared to the beginning and the end, but stick through it. It's worth it. I wish I had remained patient and stuck with it. If you intentionally find spoilers, it takes away a lot of enjoyment.
