And I'm the first person to start complaining about things that aren't quite accurate.
I discovered them a couple of years ago when a co-worker gave me one, somewhat in the middle of the series.  I expected it would simply be a good, if flawed, read.  I was completely blown away.  I promptly went to my library and started reading them in order.  They were even better than I expected.
When I saw that Tom Cruise was going to play Reacher I sighed, and have not seen the movie.  It's hard to say which matters more to me: I no longer watch any Tom Cruise movies, or the fact that physically the casting made about as much sense as casting me would.  Hey!  Let's cast a 65 year old somewhat out-of-shape and noticeably overweight woman in the part.  Honestly, I have absolutely NO experience acting, not even in high school, so I'd make almost as much sense as Tom Cruise.
I do have the newest book on reserve.  Can hardly wait.  Lee Child can't write them fast enough for me.
Among the things I like about the series is that some of them are first person, some third person omniscient.  And he sometimes mixes up the chronological time.  I sort of wish the violence weren't so strong, but that's me.
