Yea, my guess is that the primary divergence is that Netflix probably "weights" ratings of shows that are correlated with new subscribers and subscriber retention. So a low-rated show that on boards a lot of new subscribers or seems to change the behavior of a cohort who'd otherwise be expected to churn would get comparatively more credit that a show that is slightly higher watched in a vacuum, but driven by subscribers unlikely to cancel their subscriptions in the absence of the show.

Basically, any show that can show that its continued existence will result in subscribers that would not exist otherwise would likely see less ratings scrutiny than shows that cannot show this.
