1. Successful characterization: The main character in Wide Sky is the crew of the spaceship Rossinante. They were not heroes at first, they often made mistakes and looked at each other unhappily. But with the development of the story, they gradually became a close-knit family. In times of difficulty, they made heroic decisions for each other and for all mankind.

2. Excellent sound and light effect: The story is set in the 23rd century, and human beings have developed into space. There are many scenes in other planets and space in the play. Excellent photography, art and computer special effects fully show the vastness of the universe and the smallness of human beings.
