I kind of want to watch the second season. But I'm also worried, because if it leaves as much unexplained as the first season, the viewer is in for a serious slap to the face. The comedy aspect is enjoyable for the first 5 episodes. But after a while you're gonna ask yourself, "WTF?!". I had hoped for more backstories for the characters. I get it, they're weird, but without explaining why they are the way they are it's just kind of annoying. This is a Shaft production. So I'm familiar with the style of their shows. Out of all their work I've seen this, Bakemonogatari and Sayonara Zetsubou Sensei.
From reading another review it brought to light how they'll repeat a shot, such as in Zetsubou it goes back to him saying "I'm in despair.", in this it is a frequent close up of Kou's eye to show how he's freaked out by one thing or another. It works at first, but it gets a little old after a while. But that's just their style. Maybe if I watch more of their shows I'll get used to it. But I'd say for someone who hasn't seen any of the Shaft production company's work to be prepared for it! Their shows are a bit weirder than usual. The character designs are by far not the best you'll ever see. It's not plot-heavy and I'd say it's almost slapstick.
The more anime you watch the more things you become aware of will be acquainted with. I used to read bad reviews and think of them as overly cynical, but because there is so much anime out there it's hard to be original anymore. And nobody wants to keep watching the same thing over again. This show is original, but lacking in other areas.
