Review Definition and 477 Threads

A review is an evaluation of a publication, service, or company such as a movie (a movie review), video game (video game review), musical composition (music review of a composition or recording), book (book review); a piece of hardware like a car, home appliance, or computer; or softwares such as business software, sales softwares; or an event or performance, such as a live music concert, play, musical theater show, dance show or art exhibition. In addition to a critical evaluation, the review's author may assign the work a rating to indicate its relative merit. More loosely, an author may review current events, trends, or items in the news. A compilation of reviews may itself be called a review. The New York Review of Books, for instance, is a collection of essays on literature, culture, and current affairs. National Review, founded by William F. Buckley Jr., is an influential conservative magazine, and Monthly Review is a long-running socialist periodical.
