"Taxi Driver", directed by Martin Scorcese, is a great psychotic and dark film about a man, Travis, who suffers from insomnia and begins his job as a taxi driver.  As he begins developing more psychotic thoughts, the plot becomes more interesting.  The several twists and turns keep audiences' eyes wide open for every second.  The grizzly streets of New York City offer a closer, more interesting look into every event.  Such dark theme makes this film ahead of its time; in fact, some may say it's also ahead of our time.  The multiple storylines keep the plot interesting the whole time, namely a woman, Betsy, he's obsessed with and a twelve-year-old prostitute, Iris (nickname "Easy"), that he wants to help.  This leads to a powerful conclusion.  The presented quality deserved its four Oscar nominations, including Best Picture of 1976.
