The research uses Python to crawl and process the movie reviews, and then analyzes the data from the semantic and sentiment levels. The research finds that reviews mainly focus on the movie itself, the actors and the real-world impact. The high-frequency words indicate that the subtitle translation meets the audiences’ expectations, accurately clarifies the main idea of the movie, preserves the characteristics of India in a way that is acceptable to the target language readers, and triggers empathy among the audience, causing them to reflect on the reality and the situation of their own country. Sentiment analysis shows a high proportion of positive sentiments, with viewers praising the movie itself and the subtitle translation in many ways, which proves once again that the subtitle translation of the movie is a success. The translation conveys the core themes and key plots of the movie, spreading Indian culture abroad, highlighting the charm of the actors themselves, and prompting viewers to reflect on the situation of their own country. In addition, despite the relatively small proportion of negative comments, translators are reminded that subtitle translation should fully consider the acceptance of the target language audience, and avoid causing aversion due to rigid imitation.
