Reacher is one of those shows that you throw on for one episode, and suddenly it’s 3 a.m. and you’ve watched half a season. Reacher has become Prime Video’s defining action fix, and for good reason. Across four seasons, it’s nailed that sweet spot between old-school action vibes and modern TV standards. It sits comfortably at a 95% average on Rotten Tomatoes, pulls some of the biggest streaming numbers on the platform, and delivers a definitive performance from Alan Ritchson, who was almost overlooked for the role.
