Deadringer received generally favorable reviews from critics. Noel Dix of Exclaim! in his favorable review commented that the album "plays very much like the soundtrack to a motion picture". Sam Chennault of Pitchfork Media called it "an essential purchase for any fan of instrumental hip-hop". Doug Levy of CMJ New Music Report felt that "DJ Shadow may have started the instrumental hip-hop revolution, but RJD2 is here to make the coup a reality". Chris Ryan of Spin said, "[RJD2] goes spelunking for everything from flamenco and pastoral folk to the kind of raw funk breaks that most groove merchants only dream of uncovering". Tony Van Groningen of Stylus Magazine noted that "RJD2 effortlessly changes directions and adds unexpected elements to the mix that do more to perfect the songs than to muddle them up".
