Stephen Sears from "Idolator" wrote that the song "is a linguist's delight — "changes are shifting outside the word" — with a lyric about the verbal clues of a fading love affair." He wrote, "Lennox's theatrical vocal is on a high wire throughout the song, climbing up and down the scales. She made subtle tweaks to the original lyrics and added a bizarre, spoken middle eight in which she assumes a child's voice, gushing, "There are monsters outside!" The lush moment at 3:08, when a multi-tracked Lennox cascades back in, is flat-out beautiful. "No More 'I Love You's" lives as a testament to the power of the vocalist as an actor." "Irish Independent" called it a "gem". "Music & Media" commented that "it's that contrast between the superbly sophisticated cover of the Lover Speaks' 1986 soul hit and the weird intermezzo of talking and hysterical laughing that makes it so irresistible."
