This is a film where the almost invisible past crowds in on the present, compelling people (one in particular) to follow through on a devastating plan. It portrays the chaos of violence and the desolate sadness of revenge with shuddering conviction. This is not a date night movie but it is one that you should see.
The main character is depicted as a complete 'loner' but nevertheless he knows who his friends are. Without them, his mission will fail. Leadership, especially senior leadership, is a lonely position. You may feel surrounded with people who have designs on your role, and you may be right.
But the best leaders will always know on whom they can count and on whom they would depend at their peril. Being able to distinguish one from the other is key skill for leaders.
How do you know whom you can trust?
