Analyze the film. A film critic should not merely describe the plot, scenes, music, and style of the film they are studying, but also be able to analyze these elements. To analyze a film, think about how different elements work together and the effect they produce.For example, you might observe that a director uses a lot of dark colors in his film. Through analysis, you might conclude that this use of color mirrors the dark emotions of the main character. Critical essays and academic articles focus on description and analysis, while reviews usually do not.
