Yeah, I think that's the real issue. People complain about 6 episodes not being enough, but the truth is that a lot of those 6-8 episodes now feels like filler - probably because some constraints (ad cuts on scenes...) have disappeared, so writers feel emboldened. Not everything can be The Wire.
I have a friend who's written Netflix original shows, and I'll say it's the opposite - Netflix has very specific instructions for how scripts must be structured based on viewership data. Netflix knows where people tend to pause, and where viewership tends to fall off, and have formulated guidelines for scripts to counter it. They require scripts to conform to their requirements - add a plot twist in episode 2 at the 60% mark, for example. The primary character should occupy 60% of episode 1, and 40% of episode 2, and so on.
