In a contemporary review, Robert Christgau of The Village Voice said that, although its "tender passages" are not on-par with Redding's best work, Love Man is his "best LP since Immortal." Ed Leimbacher of Rolling Stone magazine wrote that the album has "several of his very strongest performances on record" and praised the "loose imagination and tight style" of the M.G.'s backing group. Leimbacher hailed Redding as a "musical genius" and called "Direct Me" "one of the best Memphis soul cuts of all time".
In a review upon its 1992 reissue, Ira Robbins of Entertainment Weekly said that Love Man has "substantial songs soaked in instrumental spirit and topped off with Redding's emotion-packed vocals."Q magazine wrote that it "showcases Redding at his up-tempo frantic and frenetic best". By contrast, Allmusic's Mark Deming felt that the album is "flawed" because of material that is weaker than his previous albums, even though it has "Redding's indefatigable energy and conviction as a vocalist and the ever-indomitable groove of Steve Cropper, Al Jackson, Jr., and the other members of the Stax Records studio crew." Matthew Greenwald of Allmusic said that, apart from "(Sittin' On) The Dock of the Bay", the album's title track was "one of Otis Redding's finest and most commercial sides that he cut at the end of his brief career."
