The central issue here is that the length of the episodes outpaces the narrative itself, a common failing among many programs on streaming platforms. It seems there are too many installments for the story being told each season. Roughly eight episodes comprise a season, but only about five genuinely advance the plot. This leads to excessive padding, creating a sense of sluggishness and ultimately feeling like little of substance is achieved. Despite this, the storyline itself holds appeal, as does the setting. It distinguishes itself from shows like A Handmaid's Tale—and many others—by avoiding a preachy tone. Still, it felt drawn out. Trimming the number of episodes to better suit the story, or incorporating a couple more side narratives, would have made for a truly exceptional series. Instead, what we get is a decent show that has been overextended and feels stretched too thin. Then came season three, which diminished the qualities that were previously enjoyable and replaced them with overt messaging; the lecturing became constant.
