Three thriller film examples are analyzed: The Perfect Guy, Split, and The Boy Next Door. All three films have male antagonists and female protagonists, and were directed by men. The thriller genre revolves around building anticipation and suspense throughout the film until a highly stressful climax. While thrillers come in different sub-genres, the analyzed piece would fit into the psychological thriller sub-genre, as it incorporates elements of drama and mystery like a psychological thriller and presents a mental/psychological threat to the protagonist rather than a physical one.
