This is a war-themed film, or rather, purportedly anti-war, different from what we're used to. Here, the purely war-related aspects-combat techniques, weaponry, uniforms-are quite neglected. Clearly, they didn't have an expert in the field, and probably didn't bother allocating a sufficient budget for this. Furthermore, it's a movie centered on psychological investigation. The setting, namely the advances of the 5th American army moving north through the Italian peninsula during WWII, is merely secondary and contributes nothing to the intended psychological exploration the director aimed to bring to the big screen.
There are numerous poorly executed or neglected details that detract from any potential strengths the film might have. The makeup, costumes, hairstyles all carry a '70s vibe that hardly makes everything else believable. Once again, perhaps these weren't the director's main focus, as they almost exclusively aimed to capitalize on a storyline that has its interesting points, but sadly, they haven't been wisely emphasized.
The actors, especially Kinski, moderately fulfill their roles, although these performances get lost in a visually flawed narrative full of imperfections and stylistic choices the director fails to control.
Technically speaking, all things related to warfare are of a very low standard, with visual stereotypes reminiscent of Spaghetti Westerns, and excessively expedient and erroneous narrative shortcuts. Weapons with infinite ammunition, soldiers from both sides dropping like flies under the enemy's endless gunfire, and a myriad of inaccuracies that undoubtedly provoke total rejection from fans of the genre towards the entire movie.
However, setting aside all these aspects, fundamentally, I believe it's a modest film that deserves more than just a passing grade since making a war-themed film when the real intent is a psychological investigation of characters-soldiers who each, in their way, carry their social, human, or racial condition-is no easy feat.
