Fistful of Dollars is a huge classic of the western genre, Sergio Leone managed to shape a typical American genre and transform it into something new.

The film has a very simple script, even though it is a little too expository, there is no great hero, who is the good guy and will do anything to end the evil, but rather a kind of anti-hero who is well worked by Leone. Clint Eastwood is the protagonist's very well-made personification, with many looks, murmurs and a tough and strong grimace.

Sergio Leone is the great genius of this film, with a more realistic view of Old West, with many detailed plans, a very good tension creation in the duels and a brilliant handling of the story, besides starting the trilogy of dollars that only improves quality as the films were produced.

The main quality of this film is without a doubt the soundtrack of Ennio Morricone, it is sensational what he brings here, with something that was not so usual for westerns of the time, impeccable and unmistakable what he does.
