Martin Scorsese may well be the greatest living filmmaker. If not, he at least ranks in the top tier of greatest directors of all time. Even when working with the fairly standard biopic genre material of The Aviator, or doing remakes like Cape Fear, he always creates a film that is simply fascinating to behold. When it comes to Taxi Driver, you could watch it on mute and still be intrigued, or with the sound up and your eyes closed, and the movie would remain enchanting.
