A bargain indeed for fans of the genre. 33 hours of viewing + bonuses. All 6 seasons + a 2008 episode set in Texas.
Bradfield in NE England clearly has more than its fair share of serial killers, enough to keep quirky psychologist Dr. Tony Hill busy for 23 gruesome cases. His skills involve being able to identify with killers and victims - he entering their minds, often disturbingly. Police grow increasingly to rely on him. Romantic undercurrents exist between him and CI Carol Jordan (Hermione Norris). Less so with Carol's successor Alex Fielding (Simone Lahbib), she struggling to do her job without neglecting son Ben.
Robson Green is excellent as Tony Hill (perhaps at times overplaying the eccentricities). He welcomes the move from "light and fluffy" roles (his words in one of the interesting bonus interviews). Nothing "light and fluffy" here! His character is constantly in danger, twice suspected of murder, several times lucky to escape with his life.
Not all is perfect. Tony's college link only occasionally convinces. In fact most of the time it is never even alluded to. Sometimes pretentiousness seems to masquerade as style with the camera work. A few cases are ludicrous, not standing up to close examination. (Judge's head on a platter, anyone?) Even these, though, are eminently watchable. Many viewers may regret the pre-credit spoilers, which - amongst other things - destroy the opportunity to reflect on what has just been seen.
For the most part the series does very well what it sets out to do. Throughout there is much that deliberately unsettles - especially in Seasons 5&6 with their marked upping of gore and erotic content.
Recommended to those who like to view what is dark and challenging.
