Simply put, this is a very poor movie. The acting was substandard... Marlon Brando stuffs his cheeks, giving himself a speech impediment which is almost unavoidable and does not make for an amazing performance, and Al Pacino walks around with a blank, emotionless face throughout the entire movie (which is the point at some times, but not the whole time). Diane Keaton also plays easily one of the most annoying roles I have ever seen in a film. Every scene in this film drags on and on and on, making it very possible to summarize the whole thing without leaving out details in around thirty seconds. The closest explanation I've gotten from anyone I've talked with in person about why this film is so great to them is because "it's the Godfather."

A movie that puts you to sleep and is not exciting or interesting does not belong as the greatest movie of all time to me.
