To start this off, I'll just say this: Do yourself a favor and buy this fantastic film. If for nothing else, buy it for DeNiro's INCREDIBLE performance! I'm a movie buff myself, and I have never seen such amazing acting. It's a crime he didn't win the oscar. Secondly, it's directed by Martin Scorsese, one of the more brilliant filmmakers of our time, and written by Paul Schrader. This is the team that brought you Raging Bull. When these two geniuses get together, they make pure movie magic. And finally, Jodie Foster. She's only fourteen years old, and beautifully brings to life the child prostitute who is secretly hating the horrible city she lives in. One of the most brilliant touches of filmmaking was made here when Scorsese portrays NYC as hell, such as focusing on the smoke spewing out of the sewers, and making Betsy, Travis Bickle's love, seem like an angel among all the demons.
The story goes something like this: Travis Bickle (Robert DeNiro) Is a taxi driver who can't seem to sleep. He works at night, and the city around him fills him with paranoia, for the gangsters and the slime on the streets at night every day seem to be everywhere. Among all of these demons and devils, Travis sees an angel, a gorgeous woman named Betsy. He immediately falls in love with her, but his anti-social tendencies scare her off when he brings her to a pornographic movie on their second date, thinking it was just like all of the other movies. When she leaves him and won't return any of his phone calls, his depression rises until he meets a child prostitue named Iris (Jodie Foster) and her pimp named Sport (Harvey Keitel). Feeling the deepest sympathy for her, he tries to help her leave that terrible lifestyle, not believing her pleas that she loves her being a prostitute and loves her pimp.
To sum this whole review up, do yourself a favor and watch this great piece of work. See Scorsese's nightmarish vision of NYC, and Travis Bickle's slow descent into insanity.
