Wrote something similar before:
"The writing has been on the wall for some time:
1. Grading system changed from 1-5 to 1-2 (thumbs up/down). They thought that the users where full of crap when rating. I do believe some bosses just looked "bad" when buying in the next Adam Sandler movie. This started a cozy culture where no one in Netflix was wrong. Recommendation engine becomes comically bad, even with the best and the brightest.
2. They started to buy everything under the sun. South park made an episode about it even. All the comedians got their own stand up specials. It was now way easier to get a top score (thumbs up). Bosses where happy.
3. As they no longer focuses on quality which they no longer can measure (measuring time watched and churn is not that useful!), they start to strive for quantity. Which is expensive, very expensive.
I guess that in the next decade Netflix will become the next Comcast and cost 35 USD per month, and it all started in an innocent change to the grading system."
