Bill Friskics-Warren of The Washington Post wrote that it "offers some of the most ebullient pop this side of old-school hit-machines ranging from Holland-Dozier-Holland to Gamble and Huff".Chicago Tribune writer Greg Kot gave the album three-and-a-half out of four stars and lauded Green's "retro-soul classicism and dark-tinged eccentricity".Slant Magazine's Huw Jones praised the album's accessibility and "buoyant nü-Motown and progressive soul", while noting Green's singing as "absolutely flawless. Pitch-perfect from tip to toe".Rolling Stone writer Jody Rosen dubbed The Lady Killer "one of the most engrossing records of 2010".
In a mixed review, Jon Caramanica of The New York Times found Green to be "reduced to an accent piece [...] purposefully restrained", stating "Green’s vocals are buried low in the mix, mere decoration for the arrangements and textures [...] crisp, lovely and certainly well rehearsed". Jer Fairall of PopMatters found the album's premise inconsistent, writing that it "feels relatively safe [...] a thoroughly likeable little trifle of a record", but added that "As a throwback, it is indeed impeccable".

Nitsuh Abebe of New York called it "suitably theatrical—a lavishly orchestrated thing", and lauded Green's dramatist "lady-killer persona" and "artifice".Los Angeles Times writer Margaret Wappler noted "a glassy modernity that makes the album a sexy sonic adventure of loving and leaving" and commented that "it’s not Green’s caddish ways that charm. Rather [...] it’s his big heart underneath".
Despite writing that "he's not always lethal", Pitchfork Media's Joshua Klein commented that Green "manages to avoid being both too rough or too smooth", complimenting his "contemporary, confident conception of soul music" and the album's "de rigueur synthetic frills". Barry Walters of Spin noted its "detailed encapsulations of Saturday-night transcendence and Sunday-morning love pains" and its music "beautifully busy 21st-century Motown as greasy as it is vibrant". Amy Linden of The Village Voice called the album "romantic—chaste, even", writing that "[Green]'s written a manual on how to both break and mend someone's heart".The Independent 's Andy Gill commented that "he manages to avoid all the bubblebath boudoir-soul cliches that litter most R&B albums".Chicago Sun-Times writer Thomas Conner gave the album four out of four stars and called it "an utter delight", writing that "every song rings fresh, modern, anthemic, packed with earth, wind and fire".
