Honestly, I consider the Japanese ecosystem to be very healthy. You have low risk webnovels, turn them into higher risk novels, higher risk manga, higher risk anime, and finally highest risk movies and video games. In this way, new blood is always entering the ecosystem, compared to the stagnant Western ecosystem which lacks a low and medium tier to test risks.
