A review is asking you to identify, summarize and evaluate the information given. You should therefore, analyze the content from a critical point of view and use your knowledge of the topic.
Ask yourself questions like:
Which is the writer’s purpose here?
Does the writer fulfil that purpose?
If so, how? Which sections contribute to the whole and to achieve the desired effect?
In the development you identify the writer’s main points and briefly summarize them. The next step would be to compare and contrast those ideas.
This can be done in different ways. No matter how many texts you have to review, you can compare their arguments and highlight how they deal with one topic or what is different. It is useful to make references to books, films, documentaries or other sources that have dealt with that topic before. You can also see how they compare with ideas and facts you jotted down about the topic before you started reading it.
Remember that the development should not be just a collection of summaries. References should be made to existing theories but your stand should also be present and show how your views differ or are similar to those you are reviewing.
In the conclusion you should consider to what extent the writer has succeed in his attempt to put his arguments forward. You can include your own feelings about the work you are reviewing and go further by encouraging the reader to experience this work himself.
