A critical essay is an analysis of a text such as a book, film, article, or painting. The goal of this type of paper is to offer a text or an interpretation of some aspect of a text or to situate the text in a broader context. For example, a critical analysis of a book might focus on the tone of the text to determine how that tone influences the meaning of the text overall. Or, a critical analysis of a film might focus on the significance of a recurring symbol in the film. Regardless, a critical essay should include an argumentative thesis about the text and plenty of textual evidence sources to help support your interpretation of the text.

Briefly state your position, state why the problem you are working on is important, and indicate the important questions that need to be answered; this is your "Introduction." Push quickly through this draft--don't worry about spelling, don't search for exactly the right word, don't hassle yourself with grammar, don't worry overmuch about sequence--that's why this is called a "rough draft." Deal with these during your revisions. The point of a rough draft is to get your ideas on paper. Once they are there, you can deal with the superficial (though very important) problems.
