What is a good rating system?
The four-point rating scale. Many organizations have used the standard three-point rating scale. However, in our research looking at the distribution of performance responses, we have found that a 4-point rating scale is often the best option to go for.
How many stars can a movie get?
Common Sense Media uses a scale of one to five, where 3 stars are "Just fine; solid" and anything lower is "Disappointing" at best. There is no agreement on what the lowest rating should be. Some critics make "one star" or a "half-star" their lowest rating.
