In her review for The New York Times, Manohla Dargis wrote, "The Good Shepherd is an origin story about the C.I.A., and for the filmmakers that story boils down to fathers who fail their sons, a suspect metaphor that here becomes all too ploddingly literal", but praised De Niro's direction: "Among the film's most striking visual tropes is the image of Wilson simply going to work in the capital alongside other similarly dressed men, a spectral army clutching briefcases and silently marching to uncertain victory".[8] Kenneth Turan, in his review for the Los Angeles Times, praised Matt Damon's performance: "Damon, in his second major role of the year (after The Departed) once again demonstrates his ability to convey emotional reserves, to animate a character from the inside out and create a man we can sense has more of an interior life than he is willing to let on".[9]

Time magazine's Richard Corliss also gave Damon a positive notice in his review: "Damon is terrific in the role - all-knowing, never overtly expressing a feeling. Indeed, so is everyone else in this intricate, understated but ultimately devastating account of how secrets, when they are left to fester, can become an illness, dangerous to those who keep them, more so to nations that base their policies on them".
