Thriller.. What Does THRILLER actually mean?...

Thriller....

Depicting crime, mystery, or espionage in an atmosphere of excitement and suspense

This is a suspenseful and sensational story or film

Usually consisted of numerous action scenes and fast paced plots

The brightest examples of thrillers are the Hitchcock’s movies.

Thrillers are mostly characterised by an atmosphere of menace, violence, crime and murder by showing society as dark, corrupt and dangerous, though they often feature a happy ending in which the villains are killed or arrested. 

Thrillers heavily promote on literary devices such as plot twists, red herrings and cliffhangers. 

They also promote on moods, such as a high level of anticipation, adrenaline rush, arousal, ultra-heightened expectation, uncertainty, anxiety and sometimes even terror. 

The tones in thrillers are usually gritty, slick and lurid.
