This document provides guidance on how to write a reaction paper to a movie. It begins by explaining that a reaction paper expresses a personal reaction and analysis of a movie rather than providing detailed analysis or judgment. It then outlines the key elements of a successful reaction paper, including focusing on themes rather than retelling the story, using proper paragraphs and grammar, and providing a three-page outline focusing on plot, themes, techniques, and an overall reaction. The document also provides examples of reaction papers and references for further assistance.
