Jack Ryan is an action packed thriller that will keep you entertained throughout the entire series and wanting more! John Krasinski has become such an amazing actor and is GREAT (as usual) as Jack Ryan! There have been a few actors that have already portrayed Jack Ryan and I have to say Krasinski is earth best so far. He really is such an underrated actor. Most people think of him as Jim from The Office but he's done so much more since then from action, drama, comedy, etc.! Even though some seasons were a little stronger than others, they're all definitely worth watching. I have really enjoyed the entire series and going to miss it now that it's gone.
