Obviously they can view what's going on to the disc first, why can't they set an audience rating that covers the entire disc? I'm not looking for any obvious answers like, "oh well they can't rate what people say in interviews," or something dismissive... I'm just trying to understand well... because in that example they can view the interviews first anyway and rate any content according to the same rules as their movie guidelines... unless if it is that simple, and there is more to the reason, like some sort of law that says you can't put a rating on someone talking? I'm just not informed in how it works, if I my example is a good guess, or there's another explanation, I just want a well explained, conclusive answer that won't lead to another question... thank you in advance!
