The Troubles were a truly fucked up conflict. The British education on The Troubles is weak, and people are generally unaware of the events that lead to the escalating violence that defined Belfast's recent history. With this context, the film does a good job of humanising and villianising all sides with a level of fairness that is not often seen in British made media about The Troubles. Soldiers are shown as both young men (often from a tough situation) with very little in the way of stakes in the fight and as the armed support for a ruthless and dehumanising state. Senior officers range from those who want to minimise the use of riot gear (because they're not their to start a riot) to those who are happy to kill their own to escalate the situation. Catholics range from the innocent, the angry, the rage-filled, the tired, and the violent. And it has a shown a decent understanding of what was happening with the IRA at this time in history, and how someone can end up involved in the IRA due to the circumstances of their lives. All of this is weaved around what is effectively a cat and mouse chase across Belfast after dark when being in the wrong part of town is a death sentence for a British soldier.
