This question needs to be answered in the context and background. However, in general, the effectiveness of literary reality and criticism is a very important issue in the pan-modern era. In the modern era, literature, as a form of cultural expression, was facing unprecedented challenges. With the continuous development and popularity of information technology, people can obtain information and knowledge more conveniently, which makes people's understanding of literary works more and more in-depth. But at the same time, this understanding also brought some new problems. On the one hand, the reality and social reality reflected in literary works may no longer be the same as in the past, but more complicated and severe. At the same time, with the development of the world and the culture, the cultural and historical background reflected in the literary works is also changing. This made the reality reflected in literary works more complicated and diverse. On the other hand, literary criticism also faced some challenges. With the continuous development of information technology, people can more easily obtain critical information about literary works, which makes the criticism of literary works more open and free. But at the same time, this freedom also brought some new problems. For example, criticism might be too simplistic and extreme, or lack depth and construction. Therefore, the reality of literature and the effectiveness of criticism became a very important issue in the era of pan-modern literature. Literature works needed to reflect the current reality and social environment, and at the same time, they needed to be able to carry out in-depth and constructive criticism of reality. Only under such circumstances could literature truly play its important role as a cultural expression and way of thinking. At the same time, the criticism of literary works also needs to be more in-depth and constructive in order to better reflect and guide the readers 'thoughts and actions.
