That depends on the type of complaint. The number of complaints is not necessarily an indicator of whether the system is working well. That has to be done is to analyze the type of complaints made. It is not the number that counts, but rather the quality. In principle, this voluntary system should have led to an improvement in the quality of the shows broadcast. However, in reality, many violent movies have been broadcast at peak viewing hours. And this number is not declining, on the contrary. The studies done by Jacques de Guise and Guy Paquet show the contrary.
