You always hear that Martin Scorsese is the best living filmmaker, and while that's really up to the individual viewer, you have to concede that he at least ranks in the top tier of movie directors of all time, alongside Kubrick, Hitchcock and Coppola. Whether he's doing his own original material as in Mean Streets or remakes like The Departed, he always puts a personal touch on the film. Taxi Driver is one of his best.

There are few directors as capable of drawing you into their world, and throughout the course of this film, you'll feel as if you're right there in the seat next to Travis Bickle. The film has a very real feel to it. It is probably as close as you can get to the feeling of "found footage" without using some gimmick like handheld cameras or The Office style interviews between scenes.

You could consider the film the second part of a trilogy with Wim Wenders' Paris, Texas, and John Ford's The Searchers, which both of the other films are loose remakes of. All three of these films tell a very similar story, and it goes to show that a movie not so much about what it's about, but how it is about it.

The Searchers was essentially an adventure film, a western revolving around unusually deep and personal themes of prejudice and lonesomeness. Wim Wenders' Paris, Texas is about lonesomeness as well as issues of family and the American Dream. Scorsese's film is the darkest of the three, revolving around the use of violence as a means to an end of loneliness. In all three, the heroes try their best to help people find their way back home, but they always stand on the outside looking in.

Each of these films is its own statement on the nature of loneliness, and it's because of this that the heroes are all so easy to sympathize with. What Travis Bickle does in the film is certainly not something most of us would ever take part in, but you find yourself wanting him to come out okay, nevertheless, simply because we all know that lonesomeness, that need for validation.

Everyone, sooner or later, feels that intense, terrible loneliness. That feeling that, even though you're surrounded by other people, you're trapped in a little bubble and incapable of breaking out and truly connecting with anyone. This is where Travis is stuck in his life, and we know that that can drive a person crazy.

What few people want to discuss, because it involves delving into your own dark side, is the part of us all that roots for Travis in the end of the film. What he does cannot be morally justified, but he does find the validation he was seeking. The tragedy is that morality isn't as simple as Travis makes it out to be.

While the film serves as part of a trilogy to The Searchers and Paris, Texas, it's also something of a companion piece to First Blood, another film about a lonely Vietnam veteran who uses violence as a means of personal validation.
