The lyrics describe the blameless end of a loving relationship.[5] Music critic Dave Marsh saw implicit feminism because the woman left the man.[6] Marsh also remarked on the maturity of the theme.[6] Music critic Robert Christgau wrote that "if there's a truer song about breaking up than 'It's Too Late,' the world (or at least AM radio) isn't ready for it."[7] Marsh described the melody as Tin Pan Alley and the arrangement as a cross between light jazz and "L.A. studio craftsmanship."[6]Rolling Stone remarked that King's "warm, earnest singing" on the song brought out the song's sadness.[8] According to author James Perone, the feel of the song is enhanced by the instrumental work of Danny Kortchmar on guitar, Curtis Amy on saxophone and King on piano.[5] Kortchmar and Amy each have an instrumental solo.[5]Cash Box described the song as "a sensitive ballad with a strong rock under-beat."[9]Record World said that it is "quality contemporary pop."[10]
"It's Too Late" has been featured in Hollywood films, including Fandango (1985), The Lake House (2006), and Invincible (2006).[14][15] Also in the sixth season of the television series Glee.
British dance music production duo Quartz (Ronnie Herel and Dave Rawlings) released their version of "It's Too Late" in 1991, introducing British singer-songwriter Dina Carroll. The song earned Carroll her first hit, reaching number eight on the UK Singles Chart.[28] It was also a top 30 hit in Austria, peaking at number 21.
James Hamilton from Music Week described the cover as a "gentle Carole King revival".[29] Anthony James from NME wrote, "'It's Too Late' should see a reversal in their fortunes. Featuring the gutsy vocals of Dina Carroll it's a truly kickin' track but with a commercial edge. Carole King will turn in her rave."[30] Another editor, Ian McCann, complimented it as "a genuine hit".[31]
Cuban American singer and songwriter Gloria Estefan released her cover of "It's Too Late" in 1995 as the third promotional single (in the US), and fourth overall single released from her fourth studio album, Hold Me, Thrill Me, Kiss Me (1994).
AllMusic editor Eddie Huffman described Estefan's version as "[a] moment of genuine pathos" in his review of the Hold Me, Thrill Me, Kiss Me album.[36] Steve Baltin from Cash Box felt that the singer "does a decent job with the vocals, but this
is one of those songs that everybody feels they own. As such, it’s better off being left alone."[37] Chuck Campbell from Knoxville News Sentinel viewed it as a "faithful" remake of Carole King's 1971 hit, "though Tim Mitchell's intrusive electric-guitar solo is an unwelcome addition."[38] Phil Shanklin of ReviewsRevues remarked that King’s voice does possess the same warmth as Estefan's.[39]
