A critical essay requires deep analysis of its subject, demonstration of critical thinking skills, and consideration of different literary theories and perspectives to ensure comprehensive exploration. It must strike a balance between objectivity and subjectivity through thoughtful examination of the topic while maintaining a rational tone. The writer must also synthesize information from diverse sources to construct a coherent argument. Finally, a critical essay demands a well-organized structure with an introduction, body, and conclusion to guide the reader through a nuanced analysis of the chosen subject.
