A mostly successful effort to reboot Paramount's successful Clancy franchise of high-tech political thrillers, this elaborate action hit is surprisingly gripping and effective for most of its running time, only fumbling with a poorly developed villain and a few regrettable clichés in its final act. Quickly becoming the American version of James Bond, the Jack Ryan character is here interpreted by the third actor in only four films, but it's a welcome surprise that Affleck delivers his second good performance in the same year. Affleck revealed a new vulnerability and emotional depth that will be welcomed by fans preferring Alec Baldwin's slightly nerdy take on Ryan over Ford's more seasoned tough-guy version. The script's conceit of returning Ryan to his young analysis-drone roots works quite well, emphasizing the character's fish-out-of-water qualities and making him a better stand-in for audience identification -- as well as giving the veteran Freeman something to play against as Ryan's wily fox of a professional mentor. A sequence involving a terrorist nuclear explosion on American soil is handled well effects-wise, and tastefully, out of consideration for real-world events only months before. However, the placement of the climactic blast at the film's midpoint, rather than later in the narrative where it belongs, serves to deflate the remaining tension. Scenes depicting the president's dickering with advisors over whether or not to launch a retaliatory strike smack of overly familiar Cold War vintage dramas such as By Dawn's Early Light, and it doesn't help that Ryan ends up grappling with a beefy neo-Nazi in a darkened Baltimore warehouse, a beat more reminiscent of a typical Barnaby Jones episode than an expensive summer blockbuster. Speaking of Nazis, Bates as the film's proto-Hitler wannabe Dressler is never quite delineated clearly, showing up only occasionally to make demented fascist-apologist speeches and then disappearing for long stretches, his evil scheme never seeming realistic enough to create a palpable sense of dread. Nevertheless, the final payoff is satisfying and for most of the journey there, the filmmakers deliver the pulse-pounding goods, ensuring further Affleck-as-Ryan adventures will be in the offing.
