Catharsis

cathartic-
is a term providing psychological relief for the audience through the expression of strong emotion when they see something on sceen (e.g villain is found)

The word comes from a greek word, Katharsis meaning 'purification' or 'cleansing' and is a sudden emotional breakdown or climax that constitutes overwhelming feelings of great pity, sorrow, laughter, or any extreme change in emotion that results in renewal, restoration, and revitalization.

We have used a cathartic experience in our opening sequince by building suspence as someone is following a teenage girl and it turns out to be her friend.
