　The purpose of this research is to build a basis for scientific analysis of critiques, by utilizing quantitative analysis for objects of critiques. Critiques about movie and theater, which are total work of arts, were selected as target, and nouns which related to objects of criticisms were extracted. Extracted words were categorized in 30 categories, and through chi-square test, evaluated elements of movie and theater were analyzed. Though there are concentrated descriptions about some individual in movie, there are characteristics of distributed descriptions in theater. Also in order to reveal relationships of those categories, those categories were analyzed using factor analysis. As a result, the differences of nuances about "director" and "acting" in movie and theater were extracted. At last, n-gram analysis is applied to extract serial patterns of categories. N-gram analysis revealed that core elements of critique logic were "story" in case of movie, but those elements were "acting" in case of theater.
