7. The Human Centipede
The Human Centipede is a rare find in the horror genre: it's so grotesque and thought-provoking that it genuinely deserves attention. In this madness of a film, a mad scientist surgically connects three unwilling victims to form a "centipede." The film is so jarring that it challenges people to confront their tolerance for on-screen violence and depravity.
On top of this, the film urges audiences to recognize the ethics behind human experimentation and science pursuits. All these have deep-seated fears of the loss of body autonomy, which turns a human being into an object of grotesque fascination. Often deemed exploitative, the movie is a thought-provoking analysis of human cruelty and forces the audience to consider the very basis of horror as entertainment.
