The fact that it's based on a true story is a big draw. It gives a sense of authenticity. You can feel the real - life experiences of the soldiers coming through. The movie also deals with themes like racism within the military, which was a real issue at that time. This adds depth to the story as it shows the additional challenges these soldiers had to face, not just from the enemy but also from within their own ranks.
One reason is its historical backdrop. It shows a part of history that many may not be familiar with. The story of the African - American soldiers in Italy during World War II is unique. The characters are well - developed, making you care about their fates. For example, the bond between the soldiers in their unit is both heartwarming and heartbreaking at times. The cinematography also adds to the allure, with beautiful shots of the Italian landscape that contrast with the harshness of war.
