It wasn't my cup of Tea, I felt we were continually tossed around with the whims of the main character. Where he himself didn't quite realize what he wanted or was needlessly vague with his subordinates, some arcs almost feel as if we were traversing through time. They did have a flashback sequence but it was quick and vague helping me remember that a lot of things happened but not quite any of the specifics or tie-ins with the story itself.
I recommend that you see one season after the other to get a better grasp of the continuation. Others commented on the action and story I do agree they are quite excellent even without a complete recollection of what is to occur though the MC is OP (almost god-like) if you are into that sort of thing.
