Yeah it's tough going by critics' opinions. They usually get it right but a lot of times it feels like they are pushing a certain social agenda that doesn't match the audience's perception.
I use Chapelle's Sticks and Stones as a prime example as I did earlier in this thread. Obviously comedy will always be the most subjective, but the critics were way off on this one. It was a hilarious special, yet they couldn't get past "wow is he really making a joke about ______ ? " And didn't seem to get the message that jokes are just jokes, and the fact they are funny is often because the topic is somewhat taboo. That's been a thing in comedy since ever. How do critics not know that?
George Lucas has your answer:
"When I started out, like everyone else I read the critics. You read not only the criticism of your own movies but everyone else’s movies, and as you start to make movies you also meet the critics. Over time I began to realize that the level of cinema criticism in the last part of this century in the United States was pretty low. The institution itself is not what it’s supposed to be, and I realized that I didn’t need to take that seriously.
There are a few critics overseas, and occasionally a critic will write an astute analysis of the movie. There is value in reading critics that actually have something intelligent to say, but the journalistic community lives in a world of sound bites and literary commerce: selling newspapers, selling books, and they do that simply by trashing things. They don’t criticize or analyze them. They simply trash them for the sake of a headline, or to shock people to get them to buy whatever it is they’re selling. The older you get, the less seriously you take it. I’ve gotten to a point now where I ignore it completely. It’s just not relevant to me anymore.
You have to have a thick enough skin to cope with the criticism. I’m very self-critical and I have a lot of friends that I trust who are film directors and writers and people in my profession. I trust them to be extremely critical but I trust their opinion; their opinion is thoughtful, knowledgeable. I also know them personally so I know the psychological slant they are putting on it. I know what their tastes are and I can say, “Well that’s great for them but that’s not great for me.” Technical criticism is extremely helpful but you are only going to get that from your peers.
I’ve discovered that most critics themselves are cinematically illiterate. They don’t really know much about movies. They don’t know the history. They don’t know the technology. They don’t know anything. So for them to try to analyze it, they’re lost. But your friends usually know what they’re doing and they can critique the technical side of things to say, “This doesn’t work. You know, you’re putting the cart before the horse.” This kind of stuff. And then the rest of it is what you like, you know. It’s personal, you know. It’s in the eye of the beholder. You know, “I like this movie. I don’t like this movie.” There are a lot of movies that are badly made that I love, and there are a lot of movies that are just beautifully made but I don’t like them. And critics have a tendency – that’s all they focus on, which is, “I like it. I don’t like it. It’s good. It’s bad.” And it doesn’t work that way, and so you really have to not deal with that part of what happens. It’s the same thing with the audience. You know, I’ve made some movies that have — ten people have gone to see. Nobody wanted to go see the movie. And some films that the people went and saw them didn’t like it. Probably, you know, maybe a half a dozen of us actually liked the movies, but that’s fine. If I like it, then I’m happy with it. And you have to sort of accept that no matter what. If nobody else likes it. You’re not going to stay in business, the business of making movies very long because you need the resources in order to keep going. So you have to try and find a niche audience or some kind of audience that has the same likes, dislikes and aesthetic sensibilities that you have."
