What critics said (Season 3): "Much like its name implies, 'Inside the World's Toughest Prisons' is all about exploring the worst of the worst. It's a relatively superficial dive into this premise, but the docuseries does a good job of immersing itself into the worlds of these criminal-filled institutions." — Kayla Cobb, Decider
