[4] Kyann-Sian Williams of NME rated the album four out of five stars and said that Nao's "honest, cinematic exploration of love, lust, and hardship makes for a compelling adventure – and one you'll happily join [her] on".

Williams concluded the review by saying that "Saturn is full of beautiful, intricately unique songs that could never be imitated.

"[2] Writing for The Guardian, Natty Kasambala said that on the album, "although [Nao's] sugary vocals have remained intact, her artistic and personal growth is evident".

Saturn falls somewhere between the dance hits of producer DJs with big-name features, and earnest, heart-tugging balladry."

Kasmbala acknowledged that along with the "rise of R&B classicists" like Jorja Smith, Ella Mai and Mahalia, "Nao presents a compelling alternative to the mainstream".
