A matter of learning to appreciate a genre. For example I like certain types of reality tv which others think is 'stupid'. But first I didn't say all reality tv and also there are things I could point out to show why it is I appreciate it to anyone watching (one is learning from facial expressions at least in people that are not botoxed). By the same token I have no appreciation of sports. I wouldn't call it 'junk' simply because I realize others have learned to really like it. But it's no different than anything else. And the reason most people wouldn't criticize sports is because they see it's widely accepted mainstream. So they are not going to be the one to go out on a limb and call it out. Although they would something else (like shooting guns as a hobby).
