If you’re the client or the boss, it’s possible that someone is going to create creative work for you.
Sooner or later, you’ll get something that doesn’t work. You might want to explain why it’s not good enough. Perhaps you can demonstrate how it doesn’t fit the genre or meet spec. Explain the historical context, the market demands and the structure of the problem and the work to be done.
That’s useful if you’re correct and clear.
Or, you might simply say, “I don’t like it.”
That’s okay too.
Frustration sets in when you should say “I don’t like it,” but try to justify it with a complicated and probably incorrect series of assertions as to why no one will.
Taste is elusive and often hard to describe. That’s okay.
But asserting that our personal, ineffable taste is also universal is probably not helpful.
