Part 3. Exercise
A History of Violence: The Best Film (2005) . David Cronenberg's "A History of Violence" is the type of film that you may not know how will wind up in the end, or what will happen next, but from the chilling starting sequence featuring what is the most violent image of the whole film, you know it's a film that's ready to raise your hairs, maybe for sheer pleasure or maybe because it's an exciting experience. The film probably shouln't be qualified as a thriller, even if it is a thriller and it is full of non cheap thrills and emotions, but as the modernization of westerns. It is, after all, a western. The character portrayed brilliantly by Viggo Mortensen is Tom Stall, and as the movie unravels we see that's he's no different to the Man with No Name or to Will Kane, for he is just the "good" cowboy, the man that we route for, the man that we want shoots the other men. As the movie advances, the plot doesn't thicken or gets more complex. As a matter of fact it's tough finding a plot so simple, yet so compelling and fun. The movie is quite fun, specially for those who like their movies to be charged with mordant black humor, and violence served in both spectacular showdowns and straight shots of blown away faces and blood splattered frames. The acting is another thing. It is the best acted movie of the year, featuring a sexy and absolutely spectacular Maria Bello, a spooky Ed Harris, who under some makeup seems like a man you don't want to mess with, and William Hurt, in a part no longer than ten minutes, but ten minutes that opaque any other film on the silverscreen. Add to that Cronenberg's direction, which filles every scene with dinamite, and every shot with visual flair and delight. As the final credits are rolling we get the sensation that this is a flawless film, and as our eyes rehearse it over and over again, we get to the conclusion that this is a flawless film. Some may say that it has no sense and that it is ridiculous, but if you think about it Munich and Syriana, and L'Enfant and Red Eye and Casablanca and almost every other movie made had the same purpose: Just to entertain. That is after all the final purpose of films, and this one succeeds high above the ground. It is also the best thriller, western, comedy and drama that has passed on the screens on a very long time.
Answer:
POS
