The Godfather by Francis Ford Coppola

There are two things that people may try to tell you about film, neither of which you are to ever believe. The first: that they know exactly what makes a movie great, this is something that just happens there is no single element that can be pointed to that makes a great film. The second is even more simple. If someone tells you that The Godfather isn't a great film you can walk away on the spot because they are an idiot. Yes, I realize art is subjective but somethings transcend likes and dislikes into the realm of greatness whether or not you like them and along with Orson Welle's Citizen Kane this is one of those undeniably great films.
