True, but I think it depends upon who is the one reviewing. For example, a person who's studied art his or her entire life would be better qualified to give his impression of a piece of art than, let's say, me.
"Better qualified" in that such a person is more familiar with the standard ways that qualitative evaluations of art are expressed in public discourse. That doesn't mean that their qualitative analysis, itself, has any more (or less) validity or relevance. In a way, art is like politics: A Senator might be "better qualified" to write laws, because they know how laws need to be structured, and what is necessary to make something into an enforceable law, but that doesn't mean that a law that that politician might promulgate would necessarily be a good law to have. It could be,
very effectively,a bad law.
(Yes, yes; I know the analogy isn't perfect. If it was perfect, it wouldn't be an analogy; it would be a tautology, eh?)
If I'm deciding what movie to see, I will take the advice of a movie critic over the advice of my dd12 (who loved Twilight, of course).
I
would go to a movie critic before an average Joe, but
only because their review would be easier to understand, more likely to indicate precisely
why they liked or didn't like the film, and therefore, based on
that information, I would be able to better determine for myself, from what the critic wrote, whether the movie was more likely to be "good" or "bad" (AFAIC). However, a "good" review, by certain reviewers, might very consistently indicate a "bad" movie (AFAIC). For example: Remember the vitriolic differences of opinion between Siskel and Ebert? What it often came down to (for me) was the good films were
only the ones that Ebert liked, and Siskel
didn't like. "Two thumbs up" typically meant I would
not like the movie, i.e., it wouldn't be a "good" movie, AFAIC.
Something similar to this often comes up in the Dining boards, when people are vigorously disagreeing with each other about WDW restaurants. ("Le Cellier is the best." "Le Cellier is horribly overrated." And so on.) What I typically suggested to people, in that forum, was to look at who was rating which restaurants which ways. I would recommend that if you know whether you like certain restaurants, you can get a feel about who's reviews you can rely on based on whether they rated your favorites highly and your least favorites poorly. I also suggested that folks try to learn about the reviewers, to see if they're "like you" or not. If they're like you, then good reviews from them may be more likely to indicate that you'd find the restaurant "good", while bad reviews from them may be more likely to indicate that you'd find the restaurant "bad". Food, television, books, movies... it all works the same way: Personal preference.
