10 Harrowing Movies You Can’t Watch Twice

Darren Aronofsky’s mind-bending adaptation of Hubert Selby's novel Requiem For A Dream is an agonising look at the progression of chemical dependency, focusing on the lives and experiences of four very different drug addicts.

The film is hallucinogenic and harrowing in equal measure, not least because you genuinely feel for the protagonists by the end. It's an eye-opening look at the people who succumb to drug addiction, shattering junkie stereotypes along the way.

Stylised directing and fast-paced editing puts the viewer inside the addled minds of the cast, making it easy to empathise with them as they drift along their downward spirals. Once it takes hold, drug addiction isn't exactly sunshine and rainbows, and Requiem For A Dream is as close as you'd even want to get to experiencing it firsthand.
