Writing reviews affords a writer an excellent opportunity to break into print and there are many categories to choose from: books, movies, theater, restaurants, art, and music. Regardless of the subject of your review, the chief purpose is to inform and though you can render an opinion, it should be supported by facts. You also need to be cognizant of the ethical conduct expected of reviewers. While there is a writing style applicable to all types of reviews, you must adhere to the specific requirements of each category.
