Steve Juon of RapReviews praised the album with a flawless 10 out of 10, claiming "Buckshot and KRS have achieved something rather remarkable here - an album I can't find a single fault with. There's not a bad beat, there's not a whack rhyme, there's not a collaborator on a track that missed the mark, and the disc itself is neither too short nor too long". AllMusic's David Jeffries stated that "loyal hip-hop heads with a taste for the old-school boom bap shouldn't think twice and won't be disappointed". Prefix Magazine reviewer called it "a call to arms, and a poetic, uncompromising one at that". In a mixed review, Andrew Rennie of Toronto-based Now said, "KRS-One's wordplay remains clever and topical, especially on the anti-Auto-Tune anthem "Robot", while his sanctimoniousness has been toned down to more tolerable levels. Black Moon's Buckshot is a comfortable pairing and, although his street-savvy sound may not have aged as well as some of his Duck Down Records brethren's, he still finds a familiar dynamic when rapping alongside old cohorts". Writing for Spin, Mosi Reeves stated that "the beats by producers Black Milk, 9th Wonder and Havoc are strictly no-frills, but just hot enough to keep these cranky yet lovable old MCs' joints from stiffening up".
