Ratings are a system used to evaluate and categorize various products, services, or performances based on specific criteria. They often use a numerical scale, such as 1 to 5 stars, to indicate quality or satisfaction. Ratings help consumers make informed decisions by providing a quick overview of how well something is perceived by others. In many industries, such as movies, restaurants, and video games, ratings are essential for guiding potential customers. They can be based on expert reviews, user feedback, or a combination of both. Higher ratings typically suggest better quality, while lower ratings may indicate issues or dissatisfaction.
