I've read/listened to quite a few Jack Reacher books, Tom Cruise was a terrible fit in the movies...the Amazon series actor is spot on to what the books describe (although the actor may be a little bit more yoked). Regarding the 'stupid gun stuff', almost every single movie you watch is full of it... I just watched a movie the other day where the 'star' was shooting a Glock...he was showing another character how to shoot...and started with "make sure you flip the safety off first"...
well...
