The only downside to the shorter seasons is book adaptations often go at breakneck pace and take too many liberties.
As example, The Last Kingdom: First two series were BBC America and 8 episodes that covered 2 books a series. Pretty damn good adaption, pretty faithful to the books even with the brutal fast pace compression, and kept the real historical basis Cornwell is famous for. Maybe a bit tame and a little too "worthy" in places. It's King Alfred christianising early England and killing many heathen Danes, some "worthy" was unavoidable. :)
Third season is Netflix and no BBC, so instant 10 episodes a series, and it's unbelievably fucking shit. The gore, the dialogue, budget and plot all got turned up to 11, all the characters got entirely new personalities and the basis on the books got thrown out the window. Yet it drags and drags, because the highlights are constant now, so no contrast any more. Cornwell's famous historical basis laughed at and pissed on. Shark jumped multiple times. In wanting to make it more showy and mass market they killed any interest of the people who did watch it.
Another reason to think my Netflix sub is nearing its end.
The only major departure from Breaking Bad on paper and Breaking Bad in reality was Jesse Pinkman. He was originally only to be a bit character in one episode, but the showrunners liked Aaron Paul so much that he became a part of, and changed the tenor of the whole show.
Is that really true? Do you have a source? From what I’ve read, Gilligan only said that as they reached Season 5. The studios didn’t know that it will be 5 seasons. maybe Gilligan had the idea in his mind since the beginning but that’s what I’m trying to say. Studios should only green light shows with a predefined length. And of course they knew the narrative. You could stretch the narrative to 10 seasons or keep it at 2. Which is the point. Keep it short.
I've been enjoying the limited-series shows, or shows that do not attempt to correlate multiple seasons together like Fargo. The first season of True Detective was done in the right number of episodes to get the story told without stringing it along. The studios forced a rushed second season that I pretend doesn't exist. HBO's Sharp Objects is another example of using just enough episodes to tell the story.
episode 1: set up the direction for some conflict/direction of the season.
episode 2 - episode n-1: a bunch of filler material with wild movements and swaps with no particular direction.
episode n: after all the wild moves, the characters and the story ended up back in pretty much the exact same place where it started.
If you care just about the story, you can legitimately skip all seasons after 2 and jump straight into the newest one without missing out on any actual story development, minus some minor references and newer characters. Which is a shame, because of how strong and directed the story in season 1 was.
At some point, it's too much. It's becoming work. And if you learn/relearn an entire world, why not something you haven't seen before? So the series gets ditched.
In my opinion, most shows would do better with far fewer seasons.
I know there are fans who want shows to go on until the whole cast drops dead of old age, but I'd much rather have a handful of seasons even for shows I really like.
