So I happen to have read the book "Make Me", that started this thread last year. It was my first Jack Reacher novel; maybe that was a mistake, as it will be my last. Too weird, and the story-telling was too linear for my taste. Stuff just happened, Reacher always stayed über-cool, no twists and turns, the bad guys are obvious, the way it will end is obvious. And the actual "mysterious" part, as I said, just weird. Not my cup of tea.
I'd actually seen the Tom Cruise movie before that and thought it was a halfway decent, but unremarkable action flick, likely because I wasn't into the books and therefore had no hang-ups about how tall he was supposed to be.
