It occurs to me that familiar plot devices appear in films because frequently they reflect what truly happens. This series presents a police detective whose commitment to his work negatively impacts his personal relationships—a common trope with characters who are law enforcement officers. However, this particular program draws from a real-life incident and the people involved. The antagonist is portrayed as excessively arrogant and malevolent, almost too much so for believability. Did he genuinely possess these qualities? Ultimately, it's beside the point, though. This is a fictionalized account, not an objective record, so some creative liberties are justifiable and even anticipated. I tuned in primarily to see Douglas Henshaw’s performance, and he delivered admirably. His character embodies determination, intelligence, intensity, and possesses just enough of those recognizable crime drama characteristics to ensure a positive outcome for the people affected by the crimes being investigated.
