The Users and Gratifications Theory argues that individuals actively select media based on their own needs and desires for information, identity, entertainment, and social interaction. The document concludes that the film "In Thus Life" will target audiences aged 16 and older, as it is a horror thriller containing violent scenes, and audiences aged 15 and over have shown greater interest in horrors than other genres.
