Ratings are a system used to evaluate and score various products, services, or performances. They help consumers make informed decisions by providing a quick reference to quality or satisfaction. Ratings can be numerical, like a score out of five, or descriptive, such as "excellent" or "poor." Different platforms, such as movie review websites or product retailers, often use ratings to summarize user experiences. These ratings are typically based on feedback from users or experts, allowing potential buyers to gauge the overall reception of an item or service before making a choice.
