Stalker is a psychological thriller television series that showcased on CBS from 2014 to 2015. The series explores the menacing and complex world of stalking, portraying the threats potentially lurking in the shadows of our day-to-day lives. The creator of Stalker, Kevin Williamson, flawlessly rides on his reputation for producing thrilling sequences from his previous works in "The Vampire Diaries" and "Scream" movie series, embodying the very definition of suspense and psychological terror in this riveting TV show.

Stalker primarily unravels in the compelling underbelly of Los Angeles, focusing its narrative on the specialized police unit known as the Threat Assessment Unit (TAU). The TAU is tasked with handling the unique, and often terrifying, cases of stalking rife in the city. By highlighting cyber harassment, obsessed fans tailing high-profile personalities, and romantic obsessions turned deadly, Stalker delves deep into the unsettling aspects of human nature and obsession. Yet, the TAU, regardless of the complexities of each case, holds steadfast in their commitment to keep their city safe.

The dynamic duo at the front-line of confronting these chilling narratives are the two leading characters - Detective Jack Larsen and Lieutenant Beth Davis. Each character is developed with impeccable attention to detail, intricate backstory, and complex personality traits that add depth to the show.

Detective Jack Larsen, played by Dylan McDermott, is a recent transfer to the TAU from New York City's homicide division. Though charismatic, Jack is trying to leave behind a checkered past and some questionable professional decisions. Despite these setbacks, he remains exceedingly persistent and dedicated in his work, and his sometimes unorthodox methods often lead to key breakthroughs in his cases.

Lieutenant Beth Davis, portrayed by Maggie Q, is the other half of this formidable team. Beth is the formidable, no-nonsense head of the unit who takes her job seriously given its personal connotations to her. As a seasoned investigator with an alluringly mysterious past, her personal experiences become an implicit driving force in her fight against stalkers. Moreover, her hyper vigilance and uncompromising demeanor make her the perfect contrapuntal character to Jack's more flexible methods.

Apart from the gripping cases that fill each episode, the show also takes time to explore the personal lives of the primary characters. The tensions and connections, especially between Jack and Beth, add another layer of intrigue to the show. Their perspectives on justice, often varied yet mutually grounded in empathy, make the series more than just another procedural drama.

Despite being a procedural show where each episode features a new case, Stalker masterfully threads a continuous storyline through the narrative, keeping audiences hooked for the series' duration. Critics appreciated its intriguing storytelling, fully fleshed-out characters, along with suspenseful cliffhangers that leave the audience pining for more. Moreover, Kevin Williamson's knack for suspenseful storytelling, combined with Dylan McDermott's and Maggie Q's nuanced acting, is the heart of the series.

This show is an intricate, heart-pumping journey into the menacing corridors of obsession, stirring questions about privacy, safety, and the disturbing lengths certain individuals will go to fulfill their desires. However, it also retains an emotional sensitivity about the terror felt by those who become victims of such obsessiveness.

In sum, Stalker is a thrilling, suspenseful series that examines the dark corners of obsession, offering viewers a perceptive exploration of how the most common aspects of modern life—like social media and public image—can be twisted into something dreadfully sinister. Its strong characters and apt use of suspense renders it as an especially memorable addition to the crime TV genre.
