24. How Green Was My Valley (1941)

Awards won: Best Picture, Best Director (John Ford), Best Supporting Actor (Donald Crisp)

John Ford has a magnificent eye for engineering lush, beautifully shot movies. His best films, like The Searchers (1956) and How the West was Won (1962), are landmarks of cinema, thrilling action-adventures that should be studied by aspiring modern-day directors.

But even the best filmmakers stumble on occasion, and Ford's 1941 kid-friendly drama How Green Was My Valley hasn't aged all that well. At two hours long, it's a tedious affair, one that feels all the more undeserving of its Best Picture accolade when you realize that it defeated Orson Welles' seminal and still exceptional Citizen Kane.
