Dishonest advertising makes you believe that "Edge of Darkness" is just another vengeance with a bang thriller. Instead this paranoia thriller is far from the conventional assembly line, far from the routine and far from the mediocre. Protracted detours and an unnecessary extended length of two full hours keep this from being a complete success. But its aim to explore big issues of corporate illegal action and its interlocked political support, while achieving this with fairly original perspectives, grips your mental interest.
