Suspense in the context of Uncertainty

Thriller is a genre of fiction with numerous, often overlapping, subgenres, including crime, horror, and detective fiction. Thrillers are characterized and defined by the moods they elicit, giving their audiences heightened feelings of suspense, excitement, surprise, anticipation and anxiety. This genre is well suited to film and television.

A thriller generally keeps its audience on the "edge of their seats" as the plot builds towards a climax. The cover-up of important information is a common element. Literary devices such as red herrings, plot twists, unreliable narrators, and cliffhangers are used extensively. A thriller is often a villain-driven plot, whereby they present obstacles that the protagonist or hero must overcome.

Crime fiction, detective story, murder mystery, crime novel, mystery novel, and police novel are terms used to describe narratives or fiction that centre on criminal acts and especially on the investigation, either by an amateur or a professional detective, of a crime, often a murder. Most crime drama focuses on criminal investigation and does not feature the courtroom. Suspense and mystery are key elements that are nearly ubiquitous to the genre.

It is usually distinguished from mainstream fiction and other genres such as historical fiction and science fiction, but the boundaries are indistinct. Crime fiction has several subgenres, including detective fiction (such as the whodunit), courtroom drama, hard-boiled fiction, and legal thrillers.

Thriller film, also known as suspense film or suspense thriller, is a broad film genre that evokes excitement and suspense in the audience. The suspense element found in most films' plots is particularly exploited by the filmmaker in this genre. Tension is created by delaying what the audience sees as inevitable, and is built through situations that are menacing or where escape seems impossible.

The cover-up of important information from the viewer, and fight and chase scenes are common methods. Life is typically threatened in a thriller film, such as when the protagonist does not realize that they are entering a dangerous situation. Thriller films' characters conflict with each other or with an outside force, which can sometimes be abstract. The protagonist is usually set against a problem, such as an escape, a mission, or a mystery.

Crime film is a film belonging to the crime fiction genre. Films of this genre generally involve various aspects of crime. Stylistically, the genre may overlap and combine with many other genres, such as drama or gangster film, but also include comedy, and, in turn, is divided into many sub-genres, such as mystery, suspense, or noir.

Screenwriter and scholar Eric R. Williams identified crime film as one of eleven super-genres in his Screenwriters Taxonomy, claiming that all feature-length narrative films can be classified by these super-genres.  The other ten super-genres are action, fantasy, horror, romance, science fiction, slice of life, sports, thriller, war and western. Williams identifies drama in a broader category called "film type", mystery and suspense as "macro-genres", and film noir as a "screenwriter's pathway" explaining that these categories are additive rather than exclusionary. Chinatown would be an example of a film that is a drama (film type) crime film (super-genre) that is also a noir (pathway) mystery (macro-genre).

Japanese horror, also known as J-horror, is horror fiction derived from popular culture in Japan, generally noted for its unique thematic and conventional treatment of the horror genre differing from the traditional Western representation of horror. Japanese horror tends to focus on psychological horror, tension building (suspense), and the supernatural, particularly involving ghosts (yūrei) and poltergeists. Other Japanese horror fiction contains themes of folk religion such as possession, exorcism, shamanism, precognition, and yōkai. Media in which the genre of Japanese horror fiction can be found include artwork, theater, literature, film, anime and video games.

Psychological horror is a subgenre of horror and psychological fiction with a particular focus on mental, emotional, and psychological states to frighten, disturb, or unsettle its audience. The subgenre frequently overlaps with the related subgenre of psychological thriller, and often uses mystery elements and characters with unstable, unreliable, or disturbed psychological states to enhance the suspense, horror, drama, tension, and paranoia of the setting and plot and to provide an overall creepy, unpleasant, unsettling, or distressing atmosphere.

The Twilight Zone is an American media franchise based on the anthology television series created by Rod Serling in which characters find themselves dealing with often disturbing or unusual events, an experience described as entering "The Twilight Zone". The episodes are in various genres, including science fiction, fantasy, absurdism, dystopian fiction, suspense, horror, supernatural drama, black comedy, and psychological thriller, frequently concluding with a macabre or unexpected twist, and usually with a moral. A popular and critical success, it introduced many Americans to common science fiction and fantasy tropes. The first series, shot entirely in black-and-white, ran on CBS for five seasons from 1959 to 1964.

The Twilight Zone followed in the tradition of earlier television shows such as Tales of Tomorrow (1951–53), Out There (1951–1952) and Science Fiction Theatre (1955–57); radio programs such as The Weird Circle (1943–45), Dimension X (1950–51) and X Minus One (1955–58); and the radio work of one of Serling's inspirations, Norman Corwin. The success of the series led to a feature film (1983), a TV film (1994), a radio series (2002–12), various literature, theme park attractions and various other spin-offs that spanned five decades, including three revival television series. The second series (1985–1989) ran on CBS and in syndication in the 1980s, while the third series ran on UPN (2002–03). The fourth Twilight Zone series, helmed by Jordan Peele, was released on CBS All Access from 2019-20.
