If, for whatever reason, you’re unfamiliar with Rotten Tomatoes, it’s probably best described as the pop culture equivalent of radon—a colorless, odorless, and tasteless gas that doesn’t directly kill you but which decays into radioactive metals that cause lung cancer. A more charitable though less evocative description would be that it’s a review aggregator that takes film critiques written by a hand-selected pool of professional reviewers, normalizes their scores, averages them, then reports what percentage of writers found the film “Fresh” or “Rotten.”
