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". Chris Malone of
Forbes said that the album registers as an "otherwise solid offering" from the singer and later added: "While the new material is a much-welcome glimpse into the mind of the singer, it also struggles in distinguishing itself from her previous albums". 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. 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." and later added that it is "far from perfect – things get much too uneven on the second half – but it's honest, emotional R&B." Antwaine Folk of
Rated R&B said: "At 13 songs, K. Michelle took no interest in carrying the torch of new-wave R&B on her first independent release. Instead, she took a fresh and even nostalgic turn that finds her remaining very much her own artist." He later added: "It's easy to listen to All Monsters Are Human and love each record without skipping one. In fact, hitting the repeat button on a few cuts is likely to happen more than once. Each song is a moment, so they should be praised back-to-back for their separate glory." 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." ==Singles==
