AP Research Idea

I've been dabbling on doing a research project about modern film preferences across Gen X and Gen Z, but I'm just having trouble knowing, what I can do to ensure my topic is specific, unique, and intriguing. I thought about acknowledging how many stereotypes can exist among generations, but also find a way to highlight the values of each generations and how they are reflected in a certain genre of film. The goal would be to determine how meaningful mainstream films are to specific generations. Let me know what I can do to improve!
