As I posted in the dupe: This saddens me. >Users would rate documentaries with 5 stars, and silly movies with just 3 stars, but still watch silly movies more often than those high-rated documentaries That's not incongruous to me. The stars are not about "enjoyment" factor, they are about perceived quality. I may have a go to cheap ice-cream and rate it 3-stars but rate a good affogato 5-stars and only have it once in…
1) How good was the movie? [1-5]
2) How likely are you to watch it again? [1-5]
I think it was too many questions to ask, but trying to separate out the enjoyment from the quality struck me as a good idea.
