18. Bug (2006)
Films don’t come much more intense than the William Friedkin-directed horror flick Bug. It focuses on the extreme mental health issues of its two protagonists as their grip on reality begins to loosen. However, while you’re watching it, you might feel like you’re starting to lose your mind too. The man behind The Exorcist released this oddity upon the world and arguably it got somewhat lost in translation. Many viewers couldn’t wrap their head around what they were seeing – ultimately the crazed interactions between two unstable people in a hotel room progressively clad in silver wrap.
17. Antichrist (2009)
Eccentric filmmaker Lars von Trier habitually shocks audiences with his projects, and Antichrist was no different. The film tells the story of a couple who are grieving over the loss of their son, with frightening events taking place soon after when they go to stay at a remote cabin. This movie divided opinion with its extremely explicit sexual content and questionable subject matter, but it also baffled many viewers with to its difficult-to-grasp plot points and abstract imagery.
16. Only God Forgives (2013)
Although visually stimulating, Only God Forgives confused almost everyone with its smattering of non-sequitur scenes and open-ended questions. The protagonist Julian – played by Ryan Gosling – is a respected figure in the criminal underworld. When his brother Billy is killed, however, Julian seeks retribution for the death of his sibling. Despite such a simple premise, the Nicolas Winding Refn-directed movie’s myriad changes of direction left many scratching their heads.
