I can't help but feel disappointed after TAXI DRIVER.  I am a huge admirer and lover of Martin Scorsese's movies, and I found yet another gem of his with this project by seeing RAGING BULL, but this movie left so much to be desired.  DeNiro's performace was more reserved than I expected, even during the violent climax,  and Scorsese's direction was much less dynamic.  I assume the story is about isolation and feeling alone in a massive, grotesque city and one man's attempt to make a connection, no matter how violent or extreme.  But it never quite kicked into the gear I would have expected.  That all being said...come on now...its DeNiro and Scorsese.  Even their worst movie is better than most other good movies.
