Whenever we consider, evaluate, and offer our opinion on something—a text, a movie, a meal, a new product—we become reviewers. Reviews are arguments that writers need to support with observations and facts. Keeping in mind a few simple strategies will help you organize your reviews.
Briefly summarize the content and state the purpose of what you are reviewing.
Assess the content. What works and what doesn't? Did you stay up all night reading the novel because you couldn't put it down? Did the ideas in the blog challenge your assumptions and lead you to discover something new? Were the vegetables overcooked? Was the actress who played the troubled teen too old for the role?
Ask yourself how others would respond. Would your sophisticated readers really enjoy the kitschy atmosphere of the dance club? Would people relate to a lead actor who seems incapable of expressing emotion? Is the blog boring after the third sentence?
Finally, to be a creditable reviewer you must appear to be knowledgeable about the subject. Presenting background about the context of what you are reviewing will help educate your readers and establish their trust in you as a source of information.
