Are movie ratings discrete or continuous?

Movie ratings are typically considered discrete because they are usually assigned in specific increments, such as whole numbers or set categories (e.g., 1 to 5 stars, or ratings like PG, PG-13, R). While the underlying quality of a movie can be viewed as a continuous spectrum, the ratings themselves reflect distinct choices made by viewers or critics. Thus, you cannot have a fraction of a star in most rating systems, reinforcing their discrete nature.
