I liked the first season too. The writing in season 3 was not good. Stereotypical characters with zero character development. Totally predictable thin plot. The acting has never been that good but it was it was really noticeable here because the dialogue gave them nothing to work with. Richter is very stiff and wooden in his moment with no athletic grace. Moves more like a local gym bodybuilder than a trained fighter.
It strikes me that multiple seasons of Reacher suffer from the same thing that happened to Childs’ books: after the first 5 or so, it’s pretty formulaic.
