The death of film criticism is proclaimed every year or so these days, as moviegoers continually declare film critics irrelevant, and box office receipts seem to be totally unrelated to critical consensus. Whenever the topic comes up, one point generally made in response is that the best way to get value out of film criticism is to do a little research and find a few critics you like rather than trying to use manufactured consensus like Rotten Tomatoes or Metacritic, which have their issues in terms of actually representing critical thought.
The most common piece of advice along these lines is to find critics who share your taste. That way, when they like something, you know you’re likely to like it, too. Conversely, you could find critics who generally like the opposite of what you do and then you can just see what they don’t like and avoid what they do. Both of these options are taking critics in their consumer guide role, and the point of reading them is to figure out what you should watch. That’s fine, but it’s pretty limited in terms of the usefulness of criticism.
Another thing I see with some frequency is to find critics you disagree with, not just to choose your entertainment contrary to their recommendations, but to provide yourself some argumentation. Reading a critic who disagrees with you can not only challenge you to see things you might not’ve otherwise, but can help you hone your reasons for liking or disliking something – that is, he/she may not convince you to change your mind, but you’ll come away with a better understanding of why you like or dislike something. This is a little more thoughtful, but tends a bit too much toward the negative/argumentative to me.
My advice: Don’t bother finding critics who agree or disagree with you. One merely reinforces your own biases, the other is only likely to set you more firmly in your ways as you defend your position (even if you only do it in your own head). Rather, find critics who make you think, and who specifically make you think about film in a different way entirely.
