Critics don't have to be directly in touch with the people. They're not paid to repeat what the audiences think in a smarter tone or writing method. They're paid to watch a film, and critique it based on their knowledge of film theory and what goes into filmmaking. If you don't agree with a critic, it doesn't mean he's a bad critic. It also doesn't mean you're a bad moviegoer. The only thing it means is that you and the critic don't have the same opinion. This is why rotten tomatoes has such a large amount of reviews from various critics for each film, so that every opinion has a form of voice.
