If I ask my kids or my girlfriend to review my code, nothing will be obvious to them. Doesn't mean that my code is the problem. The idea that the reviewer is always right makes no sense.
I can agree with that. But the intended audience for your code isn't as rigid and formalized a thing as review processes make the reviewers identities.
That actually means that review processes are usually wrong. But then, people experiences are about the wrong process, and that's what they react on.
