Given the high standard of Harrison's songwriting on All Things Must Pass, however, several of his biographers have since held "I Dig Love" in low regard and consider it to be one of the album's weakest tracks.

[5][6] With Harrison travelling without his wife, Pattie Boyd, the Delaney & Bonnie tour revealed an aspect of his persona that was at odds with his public image as the Beatle most preoccupied with Eastern religion and spirituality.

[6] Despite Harrison's strong ties to the Hare Krishna movement, whose core principles espoused a life of abstinence,[7] Bramlett later recalled him "let[ting] his hair down" on the tour,[6] in a manner reminiscent of the Beatles' pre-fame years in Hamburg.

[8][nb 1] With regard to the inclusion of "I Dig Love" on Harrison's first post-Beatles solo album, All Things Must Pass, author Simon Leng describes it as an "unusually libidinous detour", similar to the "brief sensory interlude" offered by the track "Let It Down".

[17] In his book Working Class Mystic, Gary Tillery identifies "I Dig Love" as one of two All Things Must Pass tracks (the other being "Wah-Wah") that could have been sung by John Lennon,[18] whose style increasingly embraced provocative artistic statements following the start of his relationship with Yoko Ono in 1968.

[12][25][nb 2] While Leng and Spizer credit Klaus Voormann for the bass guitar part,[12][25] Whitlock lists Carl Radle,[27] his former Delaney & Bonnie bandmate and the fourth member of Derek and the Dominos.

[31] Frequently absent from the All Things Must Pass sessions,[32][33] his co-producer, Phil Spector, had recommended in a letter dated 19 August that a synthesizer be added onto the song's intro – a suggestion that Harrison apparently ignored, according to authors Chip Madinger and Mark Easter.

[37] Author Robert Rodriguez includes the track among examples of how the musical diversity on All Things Must Pass surprised listeners, following Lennon and McCartney's dominance as songwriters in the Beatles.

"[39] In addition to receiving critical acclaim for the quality of its songs,[38][40] the album was noted for introducing Harrison as a slide guitarist,[41] a role that contributed to his signature sound as a solo artist.

[42][43] After "My Sweet Lord", "Isn't It a Pity" and "What Is Life" – all of which were featured single tracks and enjoyed heavy airplay on US radio[44] – "I Dig Love" was among the album's most-played songs in America, along with "Wah-Wah", "All Things Must Pass" and "Awaiting on You All".

[25] Simon Leng bemoans the song's "hackneyed, falling-and-rising chromatic chord pattern" and lyrics that are "probably the weakest of Harrison's career", and suggests that the 1970 outtake "I Live for You" would have been a preferable inclusion.

[47] Leng adds that Harrison's guitar solo and "particularly strong" vocal performance on "I Dig Love" "almost save the day", yet the song "lacks the expressive clout" of the rest of its parent album.
