Takashi Miike is back with Lesson of the Evil
highschool teacher goes AMOK. the one thing about this movie that surprised me is the fact that Miike got a bit soft because theres is still kinda of a happy ending which Im not used to neither is he 
but still there are some tracks left of his insanity in some scenes ..there are no words to describe the main character a happy cheerful guy without empathy lol..and the movie has no dark vibe or anything like that except some minor scenes..a very good example on how amok movies should be made. best thing is there are no stupid scene like when someone survives out of stupidity or by accident.
8/10
from Takashi Miike I also recommend
Tsubasa Ozora
Keiner kann ihn bremsen, keiner macht ihm was vor. Immer der richtige Schuss, immer zur richtigen Zeit. Superfussball, Fairer Fussball. Er ist unser Torschützenkönig und Held.
