The document discusses opening sequences in films and the concept of genre. It provides examples of opening sequences from films like Se7en and Donnie Brasco to illustrate techniques. Genre is described as a "regulated variety" that develops conventions to satisfy audience expectations. While genres allow audiences to understand new works, they also prescribe social values and may oversimplify the diversity of artistic works. The document examines how genres represent the anxieties and interests of their time periods but also serve commercial and ideological interests.
