Thriller is a genre of fiction, having numerous, often overlapping subgenres. Thrillers are characterized and
defined
by the moods they elicit, giving viewers heightened feelings of suspense, excitement, surprise, anticipation
and
anxiety. Successful examples of thrillers are the films of Alfred Hitchcock.
Thrillers generally keep the 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 must overcome.
The most common genres that overlap with the thriller genre include crime, horror and detective fiction.
