I think the more important thing is to place subtitles such as the producer's list and the sponsor's logo. Because placing it on it will not affect the movie-watching experience. Generally speaking, the opening and closing credits will include the actors' corresponding roles and the names of staff such as screenwriters, directors, etc. In addition to respecting the staff, these are also ways to express the crew's sense of accomplishment. No matter whether this drama can be recognized and applauded by the public in the end, after all, so many people spent so much time, put in a lot of thought and effort to finally complete this work. I believe that even if this drama is reviewed by later generations as the worst drama in history, at least at the moment when the work is completed, every staff member will be very excited when appreciating their work. Because no one knows the efforts behind them, only they themselves know. Of course, if the result is the opposite, not only will the sense of accomplishment increase, but it will also bring a great publicity effect to the staff in the subtitles. After all, few people want to be buried. If the work is successful, even if it is just an insignificant role in the crew, he will tell others with his head held high that he has participated in the work related to this show.
