The problem is you not understanding how Rotten Tomatoes works. If a hundred critics saw a movie and 60 did not like, Rotten Tomatoes said 40 percent. It means 40 critics liked a movie. It is not a fucking grade like high school and doesn't represent overall quality of said endeavor. It also doesn't mean you can't like something critics did not.

Furthermore, critics don't need to justify their existence when you disagree with them. That is an annoying side effect of this argument. "I disagree with the critics on said movie, and because I'm the only one with a brain, the critics are wrong. Therefore, they don't need to have a job."

Have you ever thought you are in the wrong if you like something critics didn't? You obviously like garbage and they don't.
