The Good Shepherd needed to be either considerably longer more like 1979's Tinker, Tailor, Soldier, Spy miniseries or considerably shorter. As it is, it's stuck in the deadly dull middle in which everything happens but nothing matters. The filmmakers can't stick with one event or idea long enough for it to, well, stick.
When first introduced, Edward is leaving for Cuba with his right-hand man, Ray (a valiant John Turturro). All, of course, does not go well. There's been a leak, and Edward's boss (William Hurt) suspects that it's Edward. Later, we flash back to Yale in the '30s, where Edward is revealing tales to his well-heeled brethren of a suicidal daddy who shamed the family. And not long after that, Edward's ratting out a Nazi-sympathizing poetry professor (Michael Gambon) at the request of the FBI. Oh, yes, there is time for love first with a deaf girl played by Tammy Blanchard, then with Angelina Jolie, who stumbles into the picture as a woman looking to trap the right kind of husband. (A Damon-Jolie pairing is hardly as sexy as it sounds; theirs is a glum and clumsy coupling.)
De Niro, who cameos as a secretive military man hobbled by a rotting foot, and Roth, who penned the Munich screenplay, intend theirs as a movie about the consequences of keeping secrets in the name of national security. Shepherd is supposed to be about choices mainly, the necessary choice to trust no one that break the heart and gut the soul. Yet to care about how secrets eradicate our humanity, you must first have humans, and Edward is barely that.
The story should heat up once Edward is suspected of being a mole, but Roth and De Niro, so eager to show off their meticulous research and shine a bright light onto the world of shadows, have no interest in something as conventional as a whodunit. The closest the movie ever comes to a real plot is the story involving a KGB agent nicknamed Ulysses (Oleg Stefan) and Edward's grown-up son (Eddie Redmayne), but just when the movie begins to lurch forward, we're thrown back into Edward's past in a vain attempt to reveal something more about this deep and disturbed man of great purpose and mystery.
Certainly, the plight of the average man caught up in extraordinary circumstances can work what else did Alfred Hitchcock have up his sleeve but this one great gag? But De Niro and Roth want so badly to impart the details of the spy trade, to illuminate the entire history of the OSS and the CIA, that they trade extraordinary for methodical. The hushed passing of manila folders between characters amounts to little more than tedious busywork, the spy business made routine, even mundane.
