It's so annoying to be late for the movie but finally I've got to watch the first 3 minutes. It's really a long shot, and i personally guess that the underscoring of the scene might be the most interesting one. Welles uses different sounds of, like, footstep, car horn, and broadcasting music to create an atmosphere that triggers me to "expect" something to happen on that particular car. I think its relationship between vision and sound goes quite effective, so I believe that background music weighs a lot in this movie.
The musical color in the movie is also remarkable. It differs from background sound, which pumps the sense of reality of the setting directly into my mind. Instead, Welles shots on desert landscape, the littery beard on officer Hank's face, and the filthy riverside...all these things contribute to a musical color that brings me a feeling of desolation.
The plot is fluctuant, absorbing and complete - good, for that i no need to rack my brain to conjecture what happens in the story, so i like this kind of movie in the way that saving my brain cells. Also I wanna express my praise for this plot. There is no character in the film is perfect to me, even the male protagonist, because the way Welles portrays makes me consider that this character is a fictional and typical one who is standing for justice. Well, I have to confess that i have a bias against American films, especially Hollywood ones, because many NOWADAY Hollywood productions are tragically becoming a useful instrument for those politicians to control public voice (eg. i never take those hollywood shots on mainland china or hongkong seriously), but this one might shows the truth. It reminds me of Traffic, which might also be what truely happens in US and Mexico, but that one to me is a little bit heroic and nationalist. I guess Welles tries to demonstrate the story in a "realistic" sense.
