"[13] Writing for The Guardian, Rachel Aroesti said the album "centres on the slick, soulful, 80s-style R&B that has provided the foundation for K Michelle's career".

Aroesti described Michelle's vocals on the album as "rich and glassy" and said that they are "coated in the kind of vocoder effect that makes them glitch and ripple nauseatingly".

[17] Brittany Burton of Respect wrote that All Monsters Are Human is "by far K. Michelle's biggest release to date" and also said that the most notable element of the album is the "effortless production" put into it.

[18] Edward Bowser of Stereo In Soul gave the album a positive review and rated it 3 out of 5 stars, saying that "the strength of All Monsters are Human, and K. Michelle's music in general, is her willingness to be totally transparent."

"[19] Elle Breezy of Singersroom reviewed the album, writing: "On 'All Monsters Are Human', K. Michelle seems to be in her comfort zone, delivering songs that are near and dear to her current life.

"[20] The lead single from the album, titled "Supahood", featuring American rappers City Girls and Kash Doll, was released on September 20, 2019.
