During its first season, Ansatsu Kyoushitsu (Assassination Classroom) was considered one of the best. ranked 4th in the TOP manga that sold the most in 2015.
The first live-action film premiered in March 2015 and the second will premiere in spring 2016. The manga ended in March and had 4 spin-off chapters about Koro-sensei's vacation.
I expected the same success on Monday, I wanted to see the evolution of the students, new dramas, the relationship with the teachers and the prejudice of the rest of the school. It wasn't exactly what happened in the anime and my disappointment came in the first episode when it didn't show that Koutaro Takebayashi left Class E and went to the main building.
The way this happened, how it was explored by the principal and Class E's reaction were important because it profoundly showed how they want the class to be seen by other students to strengthen the principal's idealism regarding how to educate.
Takebayashi was very inexpressive and after that event he gained a fundamental role in the following events. In the anime this was not shown and nothing was explained, not even in a narration using Nagisa.
Everything was happening very quickly, missing small things that provide the basis for both the humor and the action to be developed. Losing part of the context, the anime has been a bit dull and is losing position on the best lists. Maybe they want to go straight to the arc where the mysteries are revealed and end the anime this season by exploring the most tense and decisive part.
Even though the anime did not reach its full potential in the first part, from episode 15 onwards, the series entered a new arc, with a new opening. This arc will end the anime. You could feel the change in the atmosphere, the revelations made it clear how serious the matter is and made you think about the future of Koro-sensei and Earth.
