This is a spoiler-free review for all 13 episodes of Orange is the New Black: Season 6, which premieres July 27 on Netflix. After the curiously chaotic slog that was Season 5, which depicted a prison riot playing out in televisual "real time," Netflix's Orange is the New Black returns to its tonal and structural basics with a sixth season focusing on the riot fallout and most everyone's transfer over to Litchfield's maximum-security prison. With this shift in location, both the rioters and guards find themselves in a more rigid and dangerous sandbox, where the show's core ensemble becomes trapped in a decades-long turf war between two cruel and cantankerous sisters, Carol and Barbara (Henny Russell and Mackenzie Phillips).
