Actually, I find histograms pretty useful, primarily because if there is a secondary bump toward 1, it indicates there are a significant number of people who had bad experiences with the product -- more investigation required.
Having a two-dimensional graph might have more information, if the dimensions really matter. I'm doubtful that "stars" and "rewatchable" are really independent, and I'm unsure why I would care about it when I haven't seen the film. (If I have seen the film, I'll have my own opinion and not need the graph.)
I'm all for looking for improvements to the ratings game, though. What seems to work best for me is to actually read the reviews, but that's obviously time-intensive.
