Except you can't call mushrooms good objectively. It is evaluated subjectively, and if someone doesn't like mushrooms then to them it is legitimately valid to call it bad, even if made by Gordon Ramsay himself. Thay is the whole point of subjectivity. A bad show does not mean universally bad, it means bad in the eyes of the person calling it bad. The only thing objectively good that you could define might be the quality of the product, but not in its taste or presentation. Even a talented chef can still end up making a burnt steak.
And the talented chef analogy isn't very apt because you aren't evaluating the product, you are implying that you are judging it based on the merit of its creator. Do you think WC3 Reforged is a good game because it was made by Blizzard, a company known for hiring talented developers? They can still produce lackluster quality products despite their track record.
