Without seeing season one you can't get the complexities of the second. Only with the fist half can this be considered an actual full story; unlike some anime that can be segmented into there own separate stories. This time around everything has a very serious mood or feeling though the whole thing. Then also has ending actually is capped off really well by giving everything and everyone a clear resolution to their characters story to that point. While having it's very serious and surreal atmosphere the whole time it successfully is able to delivers it's fair share of funny moments. With this I feel itis an improvement over the first season.
