Sorry for the picture of a screen, but PS4 won't let you take screenshots in the Netflix app.
So apparently on some versions of the app, the rating system hasn't been updated to the thumbs up/down system and it still shows the stars. But because the app is pulling the rating information from Netflix and Netflix has changed their ratings to a binary "Good" or "Bad", all the ratings are either 1 star or 5.
Somehow, Catwoman is now considered a masterpiece because of this. I think that's a perfect example of why this system is awful.
