It is suitable mostly for mature audience and conspiracy theorists, even for people who do not regularly watch anime. You should keep your mind wide open while watching it. I would also recommend this anime to "V-For Vendetta" fans.
The main characters are developed enough to make someone attached to them without any unnecessary drama.
Every episode is filled with emotions of sadness, despair, anger and even romance. Suspense isn't missing either.
Even though there is a lack of realism, at least as far as we know the world, every aspect reflects on reality.
