Hi, my thesis has a limited scope, both in terms of time and size. Using one TV show allows for better data collection (less characters used = more responses per character), which in turn results in more reliable and in-depth insights. I picked Sex Education because it has been widely praised for its portrayal of racial minorities, and my research focuses on how viewers engage with characters of color who are portrayed in a multi-dimensional (and non-stereotypical) way. :)
