Focus on societal ills in British film comedy

In rpesonse to the feedback from my supervisor, I have decided to focus on issues, such as crime/ deviance, family life in British comedy, and how they try to give thier opinion on issues. By doing this, I intend to make my research more concise, as before I had to research into context, which was too broad. However, researching deeper into specific issues , will be more sufficient and wil relate to the hypothesis,' How does Britsh comedy film reflect public opinion?'
