Summary from AnimeNewsNetwork:Itoshiki Nozomu is the world's most negative person. To his way of thinking, there is no hope or meaning in this existence. Even the three kanji of his name become the two-kanji word zetsubou, "despair", when compressed. What an ironic twist of fate, then, that he becomes teacher to a class containing his precise opposite, the invincibly positive-minded Fuura Kafuka.
My Impression:Watched 2 episodes so far, and I totally love it!! Kamiya Hiroshi-san did a great job at voicing for Itoshiki-sensei, and Nonaka-san is cute as Fuura Kafuka... (what a name...)
It's satirical and funny at the same time; each character seems to have their own (strangely twisted) little stories too. The opening and endings are well-made and the OP is especially interesting =P
If you watch carefully, you'll also find lots of random scribbles on the blackboard and other places, that have references from other anime series (e.g. in ep2 we found HACHIKURO, GINTAMA and CODE GEASS references... even random BL o.0) Go check it out now! XD
