Remember that people that work in the movie industry will get free screeners or other promotional chances to view a movie before it comes out in the U.S.
Also, 428 ratings on Netflix is likely to correspond to much more than 428/# subscribers-percentage of people that have already seen it, because many people don't rate.
On Netflix, I'm not surprised to see thousands to ratings on some titles before they come out in the U.S. Usually the low hundreds pre-release indicates a smaller audience when it does come out.
