Unfortunately, there is little relationship anymore between the Jack Ryan character and the Tom Clancy novels. The last movie wasn't based on any of the novels, and the series doesn't appear to be either.
That's not to say that a Tom Clancy inspired reboot can't be successful (though I didn't care for Jack Ryan: Shadow Recruit) - the trailer looked promising...but then again I'm a sucker for All Along The Watchtower covers.
