There were many reasons why you weren't as immersed in reading novels, movies, and animations as you used to be. 1. Age: As we grow older, our mental state, emotional experience, and sensory experience will also change. This may cause us to lose our sense of involvement in certain types of literature or film and television works more easily. 2. Life experience: Our life experiences will change our aesthetic concepts and emotional preferences. For example, we have experienced more life experiences, have more interests, hobbies, and values. These will affect our understanding and acceptance of literary works and film and television works. 3. Diversion of attention: As our busy lives and stress increase, we may be distracted and no longer put all our energy into a certain work. This may cause us to have difficulty bringing in the role and emotional experience. 4. Choice of media: The media nowadays are richer and more diverse, including movies, TV series, variety shows, games and many other forms. We may choose different types of media to obtain entertainment and information, which may also affect our sense of bringing in certain types of literary works or film and television works. 5. Type of work: Different literary works and film and television works convey different emotions and topics. Some works may make us feel heavy and depressed, while others may make us feel relaxed and happy. These will affect our sense of involvement in certain types of literary works or film and television works. Therefore, there are many reasons why you are not as good as before. You may need to analyze and reflect on your own specific situation.
