Great Show, a nice reboot and look at Jack Ryan
So this really doesn't follow any of the books, because really it can't as most of the stuff for Ryan was in the '80s or earlier. Sure they could have adapted Ryan Jr, stories I guess, but they didn't. The creators decided to take the elements of how Clancy would have written Ryan, but in a modern taken. There is some sexual scenes not appropriate for children as the women bare their breasts, maybe not needed... but we got it. Just be aware if you have younger ones watching with you.
The story otherwise is amazing as it shows how Ryan deals with PTSD and becoming our hero when all he wants to do is be an analyst for the CIA.
