With the advancement of globalisation and digitalisation, the Chinese film market is rapidly becoming a force to be reckoned with in the global film industry. The purpose of this study is to investigate how emotional themes and the richness of emotional expression in film reviews afiect viewers' viewing decisions and thebox office performance of films. The average distribution and sentiment scores of each theme in the reviews of different movies are calculated by LDA theme model and sentiment analysis to measure the potential themes of emotional tendency, and the percentage of some specific emotion words in the reviews of different movies are calculated by 'WenXin' Chinese psychoanalysis system to measure the richness of emotional expression. Meanwhile, we define the box office retention rate.i.e.the box office of the second week divided by the boxoffice of the first week, to measure the influence of the potential themes of emotional tendency and the richness of emotional expression on the audience's decision to watch a flm. Through empirical research, we found that the richness of emotional expression in reviews of comedy films has a slight correlation with the audience's decision to watch the film, and the emotional richness of 'love' in reviews has a significant effect on the decision to watch the film.
