In entertainment, what is originality, that is, “authority”?

For example, in recent years many so-called “original things” have been created in the entertainment industry. One of the reasons may be business risk. If it is a popular original work or a sequel to a series that has been popular for a long time, the sales are easy to read, and conversely, it is difficult to recover the original work once it fails.

If this situation continues, Japan will end.
It is Hideo Kojima, the world-famous game creator, who calls the alarm.
