So there's the difference. Would assume most consider that entertainment should have a higher initial expectation. Like grades in school the 60% level is scraping the bottom of the barrel, and that's what many consider a 3 out of 5 star review. 66.6%. (but if you want to add in zero, then 3/5 is 50%...)
But like the polling for presidency rating, anything over 50% like you have it, is saying that it is acceptable and generally positive.
With expectations that low, i'm going to go comment on something else. Which is another value of public opinion which can't easily be determined. The numbers who do go do something else instead of commenting on the piece of culture in question.
