Oscars: Every Best Picture Winner Ever Ranked From Worst To Best

2. One Flew Over The Cuckoo's Nest (1975)

That Miloš Forman's adaptation of Ken Kesey's novel feels like a deserving winner in a year where its competition was Barry Lyndon, Dog Day Afternoon, Jaws and Nashville is all the proof you need of its excellence.

Jack Nicholson, who has arguably never been better and won the first of his two Best Actor Oscars here, leads an incredible ensemble in this deeply touching yet also surprisingly hilarious drama about a group of men residing in a mental institution.

As a matter-of-fact yet pithy precis on mental health in modern America, not to mention the battle between individuals and "the man" that was so current in the 70s, the film's constituent elements created a perfect storm of cinematic excellence that remains a much-loved masterpiece today.
