Reviewers say 'The Rocky Horror Picture Show' is celebrated for its unique blend of horror, comedy, and musical elements, creating a cult classic. Key themes include sexual liberation, rebellion, and individuality. Tim Curry's Dr. Frank-N-Furter is iconic, and the film's campy humor and memorable songs contribute to its popularity. Audience participation enhances the experience, solidifying its midnight movie status. Despite criticisms of plot coherence and production quality, energetic performances and subversive spirit make it influential pop culture.
