Could have been much worse!
Jack Ryan is a middling presence on the American Action-Hero landscape. He's no John McClane, and certainly no Indiana Jones. Jason Bourne is probably his nearest equal. They're both CIA, both in it to win for 'MERICA, and both have been played by multiple actors; Shadow Recruit's Chris Pine is the 4th iteration of Ryan, preceded by Alec Baldwin, Harrison Ford, and Ben Affleck. He carries the mantle much as he did when entrusted with playing James T. Kirk: effectively, but not in a way that makes you forget that other men, namely Ford, have done it better.
Shadow Recruit is an origin story, a tale of how Jack Ryan becomes Jack Ryan. You learn why he joins the service (SPOILER: It's 9/11), and you get to go with him on his first mission as a CIA operative (he was originally shadow recruited to be an undercover analyst sniffing out terrorism funding on Wall Street). Unsurprisingly, said first operative mission goes deeply awry and Jack must save the day (despite limited field training!).
While you're not going to see anything you haven't seen before in Shadow Recruit, it's an enjoyable ride to the finish. The tension builds nicely, and as action disaster stories go, the plot is borderline believable. It's been said before, and it's worth saying again: Sneaky fuckin' Russians, man. What's not super clear is why they're so upset with us in this movie, but hell, it's Russia. Using them as default baddie has been acceptable since the '50s.
Two major points of irritation worth noting: Kevin Costner, who plays Ryan's handler, is a bad actor. I guess a mediocre performance from the man who couldn't be bothered to do a British accent for fucking Robin Hood shouldn't be surprising, but his presence is grating just the same.
The other problem is Ryan's fiance, Cathy (Keira Knightly). She has trust issues with Jack, which, yeah, he's in the CIA, so that he'd have been a bit secretive through the years fits. The problem is those trust issues come out in fits of irrationality not befitting a sane adult, and thus don't make a whole lot of sense, given that Cathy is not only supposed to be exactly such an adult, but a highly successful one as well. Is the troubled couple arc really a necessary wrinkle when the fate of the world is at stake?
There's no reason not to make Jack Ryan movies forever. Spy/action thrillers are reliable money makers, and the character clearly works serviceably no matter who you've got in the part. Shadow Recruit isn't gonna blow you out of your seat, but it won't bore you either. Absolutely worth a look at matinee prices.
Directed By: Kenneth Branagh, who is apparently bored with being a renowned Shakespearean actor and now enjoys making kinda OK action movies.
Starring: Chris Pine, Kevin Costner, Keira Knightly, Kenneth Branagh (doing a much better Russian accent than Sean Connery did in The Hunt for Red October, by which I mean he's doing one at all).
You Should See it if: You don't feel like you can wait for it start airing on FX or TNT.
