Those figures come from a 2017 study by Pascal Wallisch and perception researcher Jake Alden Whritner, which found that our taste in movies is highly idiosyncratic - they're peculiar to an individual. The average agreement in scores among moviegoers is 26%, while the agreement between regular people and individual film critics is 27%.
'And there's some evidence, as you saw with Star Wars, that in some cases they're actually worse.' So is it generally true that critics won't predict whether you'll like a movie? 'Critics don't help you at all, they are not better than a randomly-picked person,' says Dr Pascal Wallisch, a psychologist at New York University. Another recent example is Batman v Superman: Dawn of Justice, which was liked by only 27% of critics, but 63% of the public. It isn't even the first high-profile film to illustrate that the two groups frequently disagree. But it's wrong to suggest The Last Jedi is special.
