Analyzing the sentiment of these reviews not only helps users quickly grasp the general reception of a film but also provides valuable insights for decision-making in the film industry. This study focuses on English-language reviews of the movie Inception and employs the TextBlob to perform sentiment classification. By analyzing the polarity scores of the reviews, the study determines whether viewers’ attitudes toward the movie are generally positive or negative. At the same time, the VADER was introduced as a supplement to further analyze the distribution of sentiment intensity in the reviews, enhancing the depth and multidimensionality of the sentiment analysis. The findings indicate that the vast majority of reviews exhibit a positive sentiment, reflecting a high level of audience approval for Inception. However, a portion of the reviews expresses negative sentiments, primarily related to dissatisfaction with the film’s complex plot and open-ended conclusion. This research confirms the effectiveness of TextBlob in sentiment analysis tasks and demonstrates its practical value in analyzing movie reviews, offering an efficient method for sentiment assessment in this domain.
