21. Ichi the Killer (2001)
Director: Takashi Miike
Filled with the type of beatings and torture that the makers of the Saw franchise could only hope to achieve, Ichi the Killer is an ultra-violent saga set in the seedy underworld of Japan. This is a non-stop gorefest as the mysterious Ichi and a supporting cast of killers unleash disturbing scenes of torture upon us that assault the senses and spit in the face of good taste.
And like Old Boy, this is a movie based off of a Japanese manga, but the film version far exceeds any sort of disturbing violence that could be put on paper. The character of Ichi is a programmed killer hell-bent on causing as much pain to his victims as possible, and with Takashi Miike at the helm, this combination makes Ichi the Killer a bloodbath of biblical proportions.
