Forgive what might be perceived as a stupid question: do people actually listen to or take advice from media reviewers?
Maybe? I'm leaning towards "Yes" or else Siskel & Ebert's "Two Thumbs Up" wouldn't be a thing.
All media? As far as television criticism, it, a medium that somehow has the nicknames "boob tube" and "idiot's lantern" has historically had been the lesser medium compared to movies. Whenever I read (older?) professional critics' pieces on TV shows that ain't dramas, I'm prepared to sigh at the snobbery.
I'm reminded of Roger Ebert's comments on his reviews: his essays aren't supposed to be the ultimate judgment of a work, but his sharing his perspective and trying to argue whether a work is worthy of a moviegoer's time. (or something like that, I have to look it up)
As far as today's millienials, popular YouTuber are influencers about stuff they consumer. As an avid video gamer, I notice gaming-related influencers can get a wide audience if they're witty and entertaining enough. On some forums I read, some people tout YouTubers with their personable presentation and "real" opinions as so much better than those at more established outlets like IGN/Gamespot/etc.
Anyway, as someone who dabbled in media criticism, reviews can be useful even if I don't agree with the writer's views if they're thought-provoking. Consumers should always have a discerning mind when looking for some sort of recommendation.
