Occam’s Razor. When you have two or more possibilities, the more obvious one is usually the most likely.
I start my first impressions post on the second of season of Durarara because it is one of the biggest cases of what you see is what you get I can remember in an anime sequel. The first season of the show followed a host of different characters in district of Ikebukuro, Tokyo, with stories that rarely crossed over the course of 25 episodes, only to all come together fairly well in the final few episodes. When I was wondering what I was going to get from this second season, I shouldn’t have thought quite so hard – it’s by far the most obvious possibility: much more of the same.
