Television shows whose seasons are one-and-done (or two-and-done) are pretty common in the UK. I always preferred that model, because the shows are tightly plotted from beginning to end with a complete story arc and no loose ends. Another model that works is the anthology model.
And also not having a billion episodes. The older UK standard was 6 episodes per series and so it felt like the script was also very tight, every line had to matter.
