TV crime dramas appeal to different audience groups, including mainstream families who enjoy the entertainment and escapism of exciting yet dangerous stories, niche audiences who form close bonds with complex characters, and educated viewers who appreciate learning about forensics, psychology and real-world issues through the shows. These genres attract wide interest through their use of compelling narratives, characters and settings that allow for identity, relationships and information. Audiences can actively engage by relating to situations, learning new information and discussing the shows with others.
