The Testament

Thriller is a broad genre of literature, film, and television programming that uses suspense, tension and excitement as the main elements. Thrillers... heavily stimulate the viewer's moods giving them a high level of anticipation, ultra-heightened expectation, uncertainty, surprise, anxiety and/or terror. Thriller films tend to be adrenaline-rushing, gritty, rousing and fast-paced. Literary devices such as red herrings, plot twists and cliffhangers are used extensively. A thriller is villain-driven plot, whereby he or she presents obstacles that the hero must overcome. The aim for thrillers is to keep the audience alert and on the edge of their seats. The protagonist in these films is set against a problem – an escape, a mission, or a mystery. No matter what sub-genre a thriller film falls into, it will emphasize the danger that the protagonist faces. The tension with the main problem is built on throughout the film and leads to a highly stressful climax. The cover-up of important information from the viewer, and fight and chase scenes are common methods in all of the thriller subgenres, although each subgenre has its own unique characteristics and methods.

Suspense is a feeling of uncertainty and anxiety about the outcome of certain actions, most often referring to an audience's perceptions in a... dramatic work. Suspense is not exclusive to fiction, though. Suspense may operate in any situation where there is a lead-up to a big event or dramatic moment, with tension being a primary emotion felt as part of the situation. In the kind of suspense described by film director Alfred Hitchcock, an audience experiences suspense when they expect something bad to happen and have a superior perspective on events in the drama's hierarchy of knowledge, yet they are powerless to intervene to prevent it from happening. In broader definitions of suspense, this emotion arises when someone is aware of his lack of knowledge about the development of a meaningful event; thus, suspense is a combination of anticipation and uncertainty dealing with the obscurity of the future. In terms of narrative expectations, it may be contrasted with mystery or curiosity and surprise. Suspense could however be some small event in a person's life, such as a child anticipating an answer to a request they've made, e.g., "May I get the kitty?".
