I think Moki.TV just redefined 'polarizing'. If you look at the individual bar graphs for each movie (especially the ones on the top right of the main graph), the voting distribution is actually very even ('square' or 'sloped' looking). For the data to be truly polarised you would expect the graph to be U-shaped: lots of 5s and lots of 1s and little in between.

What this data shows is that lots of people are giving these films a chance (and paying money to do so) who aren't really that engaged with the genre, or niche. That's a big validation of the studios' design strategy for the films.

An illustrative example I can think of that isn't in the top 20 is District 9: a very familiar 'niche-y' core genre, a fairly predictable plotline, but with enough influences from other genres to keep a diverse audience interested. The Dark Knight would probably be another.
