For this study, I limited my scope to Netflix scripted series produced in the United States and released globally. These are the programs for which we have the most reliable information regarding their fate, as various media outlets systematically report renewal or cancellation decisions.

Elsewhere in the world, such tracking is far less consistent, leading to significant uncertainties. I therefore chose to focus on American series, which also tend to generate the highest viewership overall.

Throughout the following analysis, I make a clear distinction between series that had a planned ending (even after several seasons) and those that were abruptly canceled shortly after their release. Some might argue that a series for which a final Season 5 is announced before its premiere is effectively “canceled” (since there will be no Season 6). However, adopting that view would imply that all series are ultimately canceled (which is technically true, I suppose). Instead, I prefer to regard them as complete works whose creators maintained control over their narrative arc until the end, rather than as unfinished projects abruptly halted mid-development, leaving their storylines without any possible conclusion.
