Compares J. Agee's film reviews for "Time" and "The Nation," concluding he assumed a more knowledgeable, sophisticated audience in readers of "The Nation." Analyzes content, style, and structure of reviews, showing loose structure, deductive reasoning, and rambling style in "Nation" reviews, and coherent, linear structure with inductive reasoning in "Time" reviews. Proposes writing assignments using this kind of analysis. (JG)
