Two pollices down
Being a critic of anything is a thankless job (that’s critic in the formal sense, not in the Internet age “I’m brilliant because I have a computer” sense). The word “critic” comes from a Greek word (doesn’t everything?) that means “able to discern,” and that’s what the best critics do — they are discerning about what they’re watching (TV/movies) or eating (food) or listening to (classical music), and then they express what they discerned in a reasoned, hopefully entertaining, way.
But, as mentioned, in the Internet age, everyone’s a critic, because everyone has an opinion, and most think that an opinion is all it takes to be a critic.
