Assassination Classroom

Heard about the live action movie for the series, Assassination Classroom, since it features ex-Kara Jiyoung.

I stumbled upon the anime today. I have to say that it started off strong!

It's essentially about a... thing with a motive to destroy the earth in a year's time. In the meanwhile, he teaches a class (apparently a weak/struggling class) about life, while the class is trying to assassinate him.

Very interesting plot line.
