It's debatable this was the motivation for Netflix. More stars ==> more nuanced ==> more qualitative reviews ==> much more effort and time to decide if you should consume. Netflix is long(er) form TicTok and wants to optimize for continued consumption without friction. I wouldn't be surprised if they drop ratings all together and only offer a personalized AI curator stream. They could do this just based on viewing time and engagement and avoid even the minor disruption of "up/down". Don't make the sheep think.
