From the highly prolific but also controversial Japanese director, Takashi Miike, who's made virtually all kinds of movies in his filmmaking career so far, Lesson of the Evil arrives as yet another twisted thriller but unlike Audition or Ichi the Killer, it's a mostly dull cinema whose only strength is its blood-soaked massacre that goes on throughout its third act.
Based on the novel of the same name, Lesson of the Evil tells the story of a very charming high-school teacher who is loved by his students & respected by his peers. His flamboyant personality however is only a mask that hides his true face, which ultimately surfaces when he decides to tackle the issue of bullying & bad behaviour among the student body with his own deranged plan.
Written & directed by Takashi Miike, Lesson of the Evil has all the bizarre elements that one usually expects from this notorious director but the story is just all-out flat, vapid & lifeless despite all the gore content it packs in. For the majority of its runtime, it's just one segment placed on top of another with no idea of where it's supposed to be headed until it arrives at its extended climax, where it redeems itself a little.
It's in the last 30 minutes or so where the movie finds its sure footing but it's a long wait to get there. The entire climactic segment has blood smeared through each n every frame and is possibly the only entertaining segment in the story and while it has the ability to shock & upset the newcomers, it's also fun in its own wicked manner for those who are pretty much used to this director's works. If only it was like this from the start.
On an overall scale, Lesson of the Evil is a brutal, violent & disturbing nightmare if one only takes the final act into account for the remainder of the story only turns it into a very boring thriller. There are plenty of interesting elements scattered around and the lead character is undoubtedly an intriguing creation but a more cohesive structure, better editing & stronger characterisation would've improved the whole experience by a significant margin.
