What BollyAI Thinks

Season 4 course-corrected sharply. Rotten Tomatoes returned to 97%, critics noting the show had refocused on its core strengths - Maslany, clone chemistry, and a body-horror conspiracy thread involving a new parasitic threat. The season's best hours recalled the tight genre thriller of Season 1 while drawing on four seasons of established character. Metacritic Seasons 4-5 were the most polished structurally, even if the show's surprise-and-expand novelty had inevitably diminished.

Season Over Season

Season 4 is the series' comeback season - trimming mythology bloat and returning to the biological body-horror that made the show's conspiracy feel personal rather than procedural.
