It's hard to say Michael Fassbender isn't fully committed in this harsh and disturbing film about Bobby Sands, the Irish Republican prisoner. Following Margaret Thatcher’s election in Britain, he found himself in Maze Prison in Belfast, where his opposition—not just to the UK but also to the largely Unionist views prevalent in Northern Ireland—led him and other inmates to endure terrible conditions that felt reminiscent of a South American dictatorship, many of which they brought upon themselves. His demonstrations seemed to be ignored, leading him to believe that only through ultimate sacrifice could he make an impact; not necessarily to resolve the issues, but with the hope of inspiring younger people, even if it meant starving himself to death. The script features dialogue that is sharp and forceful, effectively showing how fractured this community was, though ultimately it’s the stark visuals that carry most of the weight. The film doesn't attempt to present a balanced view; predictably, it’s deeply critical of Britain, but it also avoids delving into the complex historical background of the region. A significant portion of the violence within the prison came from fellow Irishmen—a group just as certain in their own convictions as Sands was in his. This lack of impartiality is where the film falters somewhat, particularly because the cinematography toward the conclusion nearly elevates Fassbender, who already possesses a face and presence suited to that kind of portrayal. Nevertheless, witnessing his gradual decline into starvation leaves little doubt that he was a man of principle who suffered greatly for what he believed in. It’s an unsettling experience that doesn't shed much light on the continuing discussions surrounding Irish unity and British identity, but it is still worthwhile viewing.
