Movie: Taxi Driver
Best Picture Winner: Rocky
Disrguntled war vet and cabbie Travis Bickle (DeNiro), a lonely man obsessed with pornography and violence. As events in Travis' life begin to turn for the worse, he slowly descends into the depths of his own paranoia, driving away the one woman willing to love him, eventually exploding in an orgy of killing against the "scum" of the streets he hates so intensely.
Rocky did deserve best picture but Taxi Driver should not be forgotten, because it is one of those movies that stays with you long after its done.
Martin Scorsese does a fantastic job with this film. It's one of those movies that you need to see multiple times in order to really see it all.
