In a one or two page paper first state what your favorite genre of film is(romantic comedy, the screen musical, the western, horror, suspense, thriller, documentary/docudrama, fictionalized biography, comedy drama, film noir, etc.)and explain why you like that genre of film.
Then choose your favorite film from that genre and describe the unique features of your chosen film and explain why it's a good representative of that genre.
The film description should be related to the genre. Simply describing the plot of the film is not sufficient.
