Summarize this article in one sentence.
Writing is at the heart of film criticism, because writing is how a film critic conveys their ideas. Make sure you have a sound understanding of organization, grammar, and style. Reading great works of literature, as well as the works of your favorite film critics, is an important step in learning to write well. Formal training in writing is not necessary, but it can help. Many employers, particularly those in mainstream media, look for film critics with a background in journalism or communication. Consider taking writing classes at your school, university, or local community college. Every film critic should offer a unique perspective on cinema that guides their work. This perspective should extend beyond individual films, and instead focus on how film as a whole relates to art, society, or politics. Some critics believe that film can offer guiding wisdom to help people live better lives. Others believe that every film element has a significant symbolic value. To develop your own guiding philosophy, think about what film means to you as an art form and how it relates to life. Be honest in your critiques of films. Don’t bash a film just for dramatic effect. At the same time, don’t be afraid to speak out against a film that other critics have praised. People read film critiques for the ideas and opinions they contain, not for artistic writing style. While your pieces should be well written, avoid using flowery language or technical jargon, which can detract from clarity. While you’ll be constantly offering critiques of others’ work, you should always remain critical of your own. Try to find the weaknesses in your arguments, and address them. A finished critical piece should be the product of multiple drafts.

Summary:
Learn how to write well. Develop a guiding philosophy. Be honest. Use simple language. Critique yourself.
