Il était une fois la révolution
"Duck, You Sucker!" failed to gain any substantial recognition from the critics at the time of debut, especially compared to Leone's other films, though he did win the David di Donatello for Best Director. Since then, however, it has received a more favorable reception: on review aggregator Rotten Tomatoes, the holds an approval rating of 92% based on 24 reviews, with an average rating of 7.40/10. The website's critical consensus reads, "Duck, You Sucker" is a saucy helping of spaghetti western, with James Coburn and Rod Steiger's chemistry igniting the screen and Sergio Leone's bravura style on full display". The "Chicago Reader" praised it for its "marvelous sense of detail and spectacular effects". "The New York Observer" argues that Leone's direction, Morricone's score and the leads' performance "ignite an emotional explosion comparable to that of "Once Upon a Time in the West"". In Mexico, where the film is known as "Los Héroes de Mesa Verde", it was refused classification and effectively banned until 1979 because it was considered offensive to the Mexican people and the Revolution.
