Netflix's system wasn't so much a thumbs up/thumbs down system that we all know and love - it was a frankenstein system where you couldn't see how many thumbs up/down a title had, rather you saw a percentage on how likely you are to enjoy that title based on the thumbs you gave others. At first glance it looks like YouTube's system but in actuality it was very different.
