The best I think we can achieve is to akin to finding movie reviewers we like, but also to listen to those we don’t.
We discover reviewers (amateurs count) who like the same kind of films and have shared pet peeves with us. Knowing WHY a movie reviewer likes or doesn’t like a film though is supremely important. "I found the costumes too colorful" my be exactly something we want to watch. "I thought it was a documentary, but it was a musical and I hate musicals." Those sort of salient details make a reviewer much more useful than a thumbs up/thumbs down type of taste maker.
And that’s a pet peeve of my own. I can respect the preference of someone who loves brand X - but if they don’t give me some details about what they like about it, what other brands they tried before, and what speakers they are listening to this fanboy commentary doesn’t help me very much at all. All I've learned is that Susan loves X and doesn't like Y. Well, that helps me not one bit.
Best,
E
