Jack Reacher has built his reputation on being the guy who sees the puzzle, cracks the puzzle and then handles whoever gets in his way. Season 4 does something Alan Ritchson’s Jack Reacher really hatesThe shift begins with a subway incident that drags Reacher into a case he cannot immediately explain. Alan Ritchson sees that uncertainty as an important crack in Reacher’s armor. After Season 3 matched Reacher against Olivier Richters’ towering Paulie, the series decided against simply finding an even larger opponent. This time, the biggest threat may not be someone he can simply punch into getting answers, and that could be exactly what makes Season 4 interesting.
