"Taxi Driver" is a brooding, sometimes violent character study. Although controversial, it has generally been highly praised. While it is a good film, it lacks focus, and De Niro's character transitions sometimes lack credibility.

A very lean Robert De Niro is Travis, a taxi driver in New York City. Travis is a loner, spending off hours in porn movie houses and brooding alone in his apartment. He keeps a journal in which he condemns the street life of NYC, and wishes that somebody would clean the city up. He develops obsessions for political staffer Cybil Shephard, her Presidential candidate Senator Palantine (Leonard Harris), handguns, and a twelve year old prostitute (Jodie Foster).

The climax of "Taxi Driver" has the heavily armed De Niro attempting to rescue Foster from her pimp (Harvey Keitel, who has shoulder-length hair). This results in a graphic shootout. I don't object to the bloodfest, but its aftermath. It is as if nothing has happened: Travis is again working as a cab driver, and has recovered his mental faculties.

After Shephard's brief relationship with De Niro ends, her character keeps resurfacing. This is as confusing to me as De Niro's actions. He attends a Palantine speech, apparently to assassinate him, with the assumed motive of impressing Shephard. But by this time, his interests have turned to Foster and Keitel. The Bernard Herrman score, good as it is, increases the confusion, changing back and forth from sleepy retro jazz to something more brooding and ominous.

"Taxi Driver" is a very interesting film. It is impossible to predict where the story will go next, the dialogue is very good, and the cast and direction (by Martin Scorsese) is good. Palantine, a stereotype of an ambitious, platitude-spouting politician, is the only weak character.
