AllMusic editor David Jeffries praised the album for Medasyn's production and Sovereign's lyrical content for being relatable, calling it "an exciting introduction to an extraordinary artist captured at just the right time." Michaelangelo Matos of The A.V. Club compared the album to The Sex Pistols, praising tracks like "Tango" and "Hoodie" for their angst-filled energy, saying "Even if Sov doesn't cross over the way she or Def Jam might want her to, she still sounds like an original—even for people who know half the songs already." Mike Diver of Drowned in Sound praised the album for having solid production and lyrical content that's both gritty and humorous, saying "When her tongue's in cheek and her rhymes amuse, Lady Sovereign is hugely entertaining." Michael Endelman of Entertainment Weekly found criticism in the album's overly frenetic beats and out-of-tune choruses but praised Sovereign for her humor and lyrical flow, saying that her "rubbery rhymes and punky energy are definitely entertaining, and well worth sampling in moderate doses." Steve 'Flash' Juon of RapReviews commented that Sovereign's heavily accented lyrics and electronic beats can get abrasive at times but said the album has crossover potential because of her flow and humor that requires little British familiarity. The album also received negative reception from critics.
