A review should be divided into three sections - an introduction, main body, and conclusion. The introduction should mention what is being reviewed, such as a book or film, and provide an overall description. The main body should expand on key aspects like plot, characters, and acting through paragraphs, and discuss whether the plot was gripping or disappointing. The conclusion should provide an overall evaluation of whether the reviewer would recommend it and why or why not based on the aspects discussed. The review should use formal language and avoid contractions.
