"The Earth's moon is suddenly 70% smaller and permanently crescent shaped by a devastating and unknown force. For the students of E Class, Kunugigaoka Junior High School, the being responsible is known, as their teacher. The strange and very supportive entity has given the Japanese government a challenge to save the Earth from destruction. It wants to be the teacher of the class with the lowest expectations for success, in anything. The students, armed with special weapons that only harm their teacher, must find a way to kill him before the end of the school year. If not, summer break will be canceled by the end of the world."
Assassination classroom is another Manga live action adaptation in the vane of Parasyte and it's equally bonkers if not more so.
Weird aliens have destroyed three quarters of the moon and one of the aliens has come to earth to teach a young class to be assassins. The Alien is octopuss like with the classic "Smiley" face and his face changes colour dependent on his mood and he requarly sheds his skin. He also offers a reward to the class to anyone who can kill him. If his face turns red get out of his way!
It moves at a million miles an hour so the task is not easy by any means. During the movie they have new students transferred to the classroom who are pretty bad ass and certainly a challenge to the teacher. One stand out scene is when a student arrives who also has tentacles and there is a great stand off and fight.
And also great news there is also a follow up which I will definitely tracking down. Assassination classroom: The Graduation is coming this year!
As with many Manga adaptations it can get a little confusing at times but all in all pretty coherent.
The CGI is superb and the characters are brilliant. It's violent and hilarious in places. Well worth seeking out.
