If you don't see this movie Brando will hunt you down and cut off your head...
In all seriousness, this movie is a true piece of cinematic perfection. The rising tension present in this movie balances perfectly with the way the characters unravel before our eyes. Brando, Sheen, and Duval all put in performances for the ages that give great added depth to their characters. Also, a little known fact is that a cow was actually butchered during a scene in this movie, so if you're looking for the Humane Society seal of approval, I'd suggest you hug a tree instead and then pick yourself up a copy of this movie. Take the time and watch the director's cut to see Coppola's real vision of the movie.
