‘Magnum P.I.’ (1980–1988)

A classic ’80s TV show that made Tom Selleck into a global TV legend, Magnum P.I. stars Selleck as the titular ex-military officer working as a private investigator and solving crimes across Hawaii. Unlike conventional TV detectives, Thomas Magnum lives a luxurious life as a permanent guest at a sprawling beachside estate owned by a wealthy author, where he enlists the help of his veteran friends and the estate’s stiff-upper-lipped English manager to solve his cases. John Hillerman, Roger E. Mosley, and Larry Manetti play the other main characters.

Created by Donald P. Bellisario and Glen A. Larson, Magnum P.I. was a unicorn of its genre at the time and relied on its self-contained stories that feel consistently refreshing in every season. It instantly gained attention for swapping grim for glossy and presenting a charismatic detective who is also grounded, which became the winning formula for the show. A detective show that made aloha shirts and thick mustaches trend in the ’80s, Magnum P.I. is a cultural touchstone of its time and an American television landmark.

A multiple Emmy Award-winning crime series created by Andy Breckman, Monk follows the titular former San Francisco detective, Adrian Monk, whose wife’s mysterious death aggravates his existing phobias and obsessive-compulsive disorder. Known for his unique crime-solving methods and strange insights, Monk becomes an outside consultant working with the SFPD, while investigating his wife’s murder and being perpetually annoying about his afflictions. Tony Shalhoub leads the cast, immortalizing the character of Monk, with Ted Levine, Bitty Schram, Jason Gray-Stanford, and Traylor Howard as other main cast members.

Balancing between a sharp detective and a hyper-eccentric man with debilitating issues, Adrian Monk completely subverts the image and expectations of a hero detective, bringing a whole new angle to conventional police procedurals. Headlined by great performances from the main cast, every season of Monk is a delight with its unconventional hero, interesting crime stories, and even more interesting investigative techniques. Ranking among the best crime shows of this century, Monk is as cozy, comforting, and abundantly hilarious as a detective series can get.

Joe Penhall’s adaptation of John E.

A modern update on Sir Arthur Conan Doyle’s Sherlock Holmes stories, Elementary finds the London detective in 21st-century New York City, reimagined as a recovering addict.

Created by Robert Doherty, the ABC show stars Jonny Lee Miller as Holmes and Lucy Liu as Watson, with Aidan Quinn, Jon Michael Hill, and John Noble as main characters.

Elementary is not just a reinvention of Sherlock Holmes but a quiet tribute to the motifs and themes of the original mystery literature classics.

An exciting and high-energy detective show, Elementary is critically praised for the satisfying narrative and its unique personification of Sherlock Holmes.

A crime television legend, David Simon’s The Wire is not a conventional detective show and involves a wide range of investigations within different institutions of the city of Baltimore. The story is told primarily from the POV of a renegade cop, Jimmy McNulty, whose investigation of the local drug lord and his right-hand man sparks a chain of events that expands to various city departments. All five seasons star Dominic West, John Doman, Lance Reddick, Wendell Pierce, and Andre Royo as main characters.

One of the best crime shows of the 2000s, The Wire has been lauded for its impressive writing and surprisingly accurate depiction of society, politics, and urban life in modern America. The show shifts from standard police procedural tropes and uses the interconnectedness of every city institution to drive individual character arcs, with the city of Baltimore as the main protagonist of the story. The result: an engaging, new chapter unlike anything you’ve seen before in every single season.

In BBC’s Sherlock, Steven Moffat and Mark Gatiss reimagine the original canon of Sherlock Holmes stories by Sir Arthur Conan Doyle in 21st-century London, where Sherlock is a quirkier and more eccentric truth seeker and crime solver. With the help of his new roommate turned friend and confidante, Dr. John Watson, and the latest tech he can get his hands on, Sherlock helps Scotland Yard solve the most unsolvable modern crimes. Benedict Cumberbatch stars as Sherlock and Martin Freeman as Dr. Watson, with Rupert Graves, Una Stubbs, and Gatiss appearing in key roles across all four seasons.

A brilliant 21st-century interpretation of the legendary British detective, Sherlock thrills, awes, and excites fans with slick plots, sleek tech, and plenty of pop culture references. The show is noted for its tight-knit storytelling and incredible cinematography in every season. Each only features a few episodes, all of which are sharply written and perfectly acted. Despite the criticisms and controversies surrounding the later seasons, Sherlock remains a fine modern adaptation of Sherlock Holmes anchored by Freeman and Cumberbatch’s unmatchable chemistry, and even its relatively worse seasons are genuine masterpieces.
