In this day and age, we have no shortage of shows like these. Stuff like "Reacher", "Shooter", "Taken", "Punisher" and "Terminal List" all roughly scratch the same itch for a grounded gun guy vs government goons TV series. It becomes increasingly difficult to stand out when the series is based on books written roughly 30 years ago. I mean Tom Clancy has been dead for 10 years now. That might explain why so many of his stories involve some spark that will make the Cold War escalate to World War III between America and Russia. Most of Clancy's material has been mined in other films and even video games that anything now seems derivative. Similar to Jane Austen with romantic comedies, so it is with Clancy and political thrillers.
Well then, the difference has to come from the character. What makes Jack Ryan different than Jack Bauer? What made him a charming protagonist was the fact that he didn't have, as Bryan Mills would say, "a particular set of skills." Ryan is an analyst, a desk jockey. He was the everyman thrown into difficult situations outside his control.
I feel that edge is where "Jack Ryan" misses the mark. This Jack Ryan, particularly by the third season, is just the same type of action tough guy as every other political thriller show. It's not bad, just every change they make to Jack Ryan makes him more generic. They are making him out to be more like John Karasinki's character from "16 Hours".
That being said, they do an excellent job with the action in this show. The music, cinematography and acting are all top-notch. The political intrigue and stories are well done. I just wish it would appeal more to the everyman angle that makes Jack Ryan so unique.
