You can agree or disagree with the writer but each claim or point you make has to be supported by strong evidence and arguments that prove your analysis of the author’s point.
Each student should know how to cope with critical analysis.
The idea is to reflect your opinion on the specific text.
You don’t have to focus merely on the negative points.
Your review should provide information, interpretation, and evaluation.
The information will help your reader understand the nature of the work under analysis.
The purpose for writing a critique is to evaluate somebody's work (a book, an essay, a movie, a painting...) in order to increase the reader's understanding of it.
A critical analysis is subjective writing because it expresses the writer's opinion or evaluation of a text. Writing a critical paper requires two steps: critical reading and critical writing.
The interpretation will explain the meaning of the work, therefore requiring your correct understanding of it.
The evaluation will discuss your opinions of the work and present valid justification for them.
