Critical response
Buzz McClain of The Washington Post called Jackson's version "a hook-filled number that zips from ballad to rocker and back again."

Iain Ellis of PopMatters described Jackson's performance: "Honing her Elvis-style hiccup vocal, Jackson satirized the prevailing male hits of the day, songs that posited either romantic illusions or 'cool' boasting. Rather than passively wallowing in these conceits, or swallowing their deceits, Jackson set to de-bunking them with brutal 'response' lyrics."

Billy Poore wrote that it "starts out like a sad, sappy country ballad, and then all of a sudden, Wanda just roars into the meat and potatoes boppin' rockabilly sound."
