So, a movie can only be two thirds good, or perhaps one third good? That makes little sense. Why not say 'this movie is good' or 'this movie is bad'?
It's not that the movie is two thirds good or one-thirds good.
It's that there is a spectrum of movie quality. That quality is subjective. For example, an online friend gave Transformers five out of five stars, meaning that on her spectrum of movie value, movies can't get any better than Transformers. I, on the other hand, gave Transformers three out of five stars, meaning I like it better than about half the movies out there but not as much as about half the movies out there. The number of stars is not a discrete count, it is a relative value.
Then the site that keeps track of the stars averages out everyone's personal assessments of quality. If only my friend and I voted on Transformers, the site would say it had four out of five stars because the average of three and five is four. This is how a site can have something like 3.75 because averages don't always come out to whole numbers.
Once hundreds of people vote on a film, the average starts to have some meaning -- if a film has two stars, it's probably not that good but might be watchable if it's a genre and subject someone tends to like. If a film has 4.9 stars, it's probably terrific and destined to be a classic (or is a classic already.)
So what it means when the movie appears to be "one-third good" is that, on average, people like it better than about a third of the movies they've seen but not as much as about two-thirds of the movies they've seen.
