The 1970's are widely regarded as perhaps the most artistically exciting era in film, and "Taxi Driver" stands as one of the finest films of that great period and 30 years later, "Taxi Driver" is still Scorsese's best film and one of the greatest films of all time.  If, for whatever reason, you have any interest in films at all and still haven't seen "Taxi Driver", don't put it off another day.
