The Tunnel

The Tunnel is a compelling crime drama that aired on PBS from 2013 to 2018. This Anglo-French series is an adaptation of the original Swedish/Danish show "The Bridge" and was created by Hans Rosenfeldt, Måns Mårlind, and Björn Stein. This gritty series blends the themes of crime, mystery, and escalating international tension, making it a must-watch for fans of this genre.

The show kicks off when a high-profile French politician is found dead on the border between the UK and France. But this isn't a straightforward crime scene - the body is found right on the dividing line in the Channel Tunnel, presenting jurisdictional nightmare for the law enforcement agencies of both countries. To solve this cross-national crime, two highly competent yet vastly different police detectives are forced to join forces.

Karl Roebuck, portrayed by Stephen Dillane, is a seasoned British detective with a tendency for sarcastic humor and a laissez-faire attitude towards protocol. His partner is Elise Wassermann, played by French actress Clémence Poésy, who is meticulous in her work, incredibly focused, and has Asperger's Syndrome. The contrast in their methods, attitudes, and ways of coping with horrific crimes creates a dynamic relationship, providing depth to the series without deviating from the critical storyline. Their partnership is a central theme, representing not just the confluence of two distinct cultures and law enforcement approaches, but two unique personalities and life philosophies.

The storyline of The Tunnel is carefully crafted, maintaining a suspenseful atmosphere throughout. The plot transcends the initial crime to expose an intricate web of deceit and criminality across Europe. As the duo unravels the mystery, they navigate a series of increasingly sinister events full of dark twists. The execution of the storyline successfully intertwines individual narratives with the main plot, offering philosophical insights into complex socio-political themes including immigration, international relations, terrorism, and national security.

Furthermore, the locations are striking in their own right. The contrast between the bright cliffs of Dover and the industrial aesthetics of Calais adds visual narrative depth to the series. The setting in the titular Channel Tunnel underscores the duality experienced throughout the show - its claustrophobic environment amplifies the suspense while symbolically representing the tumultuous relationship between the UK and France.

The Tunnel's direction and cinematography are infused with chilling detail, which enables viewers to fully immerse themselves in the suspense-rich world of cross-border crime. Moreover, the show also features a solid supporting cast, each bringing their separate elements to the table, making the procedural crime drama even more engaging and multidimensional.

The series is also laudable for its unflinching portrayal of complex lead characters, as it move past typical archetypes seen in police dramas. Roebuck’s casual charisma paired with his unorthodox working style is beautifully balanced by Wassermann’s precision, dedication, and her struggle with social nuances due to Asperger's Syndrome. Their banter, mutual respect and eventual friendship add a strong undercurrent of human emotion amidst the larger geopolitical and criminal turbulence.

This series, while providing the thrill of unraveling crimes, also offers an intelligent exploration of political and personal themes. Its ability to maintain emotional poignancy while focusing on an unflinchingly harsh reality is one of its defining strengths. It challenges viewers to contemplate moral dilemmas, creating a psychodrama within a procedural crime narrative.

To sum up, The Tunnel is a gratifying watch, full of emotional depth, impressive performances in addition to compelling plots stitched with unexpected twists. It seamlessly blends an engrossing crime narrative with psychological explorations and socio-political commentary. The intense collaboration between two unique detectives to solve cases of such magnitude against the backdrop of two contrasting locations makes this an exceptional addition to the genre. With its gripping storylines, intriguing characters, splendid performances, and socio-political subtexts, it makes for compelling viewing.
