At the time of the album’s release, which followed the up-tempo single version of the song, Revolution, in which Lennon definitely wanted to be counted out,, that single word in was taken by many on the radical left as Lennon’s acknowledgment, after considered thought, that violence in the pursuit of political aims was indeed justified in some cases. At a time of increasing unrest in the streets and campuses of Paris and Berkeley, the album’s lyrics seemed to many to mark a reversal of Lennon’s position on the question, which was hotly debated during this period.

However, the recording chronology belies the interpretation that from the single to the album Lennon moved from a definite position to one of ambivalence, since despite the single’s earlier release it was the album version that was recorded first.

On release, The Beatles gained highly favourable reviews from the majority of music critics. Others bemoaned its length or found that the music lacked the adventurous quality that had distinguished Sgt. Pepper. According to the author Ian Inglis: “Whether positive or negative, all assessments of The Beatles drew attention to its fragmentary style. However, while some complained about the lack of a coherent style, others recognized this as the album’s raison d’être.”

In The Observer, Tony Palmer wrote that “if there is still any doubt that Lennon and McCartney are the greatest songwriters since Schubert”, the album “should surely see the last vestiges of cultural snobbery and bourgeois prejudice swept away in a deluge of joyful music making””a major success” and “far more imaginative” than Sgt. Pepper or Magical Mystery Tour, due to the band’s improved songwriting and their relying less on the studio tricks of those earlier works. In The Sunday Times, Derek Jewell hailed it as “the best thing in pop since Sgt. Pepper” and concluded: “Musically, there is beauty, horror, surprise, chaos, order. And that is the world; and that is what The Beatles are on about. Created by, creating for, their age.” Although he dismissed Revolution 9 as a “pretentious” example of “idiot immaturity”, the NME’s Alan Smith declared “God Bless You, Beatles!” to the majority of the album. Jann Wenner of Rolling Stone called it “the history and synthesis of Western music”, and the group’s best album yet. Wenner contended that they were allowed to appropriate other styles and traditions into rock music because their ability and identity were “so strong that they make it uniquely theirs, and uniquely the Beatles. They are so good that they not only expand the idiom, but they are also able to penetrate it and take it further.”

Among the less favourable critiques, Time magazine’s reviewer wrote that The Beatles showcased the “best abilities and worst tendencies” of the Beatles, as it is skilfully performed and sophisticated, but lacks a “sense of taste and purpose”. William Mann of The Times opined that, in their over-reliance on pastiche and “private jokes”, Lennon and McCartney had ceased to progress as songwriters, yet he deemed the release to be “The most important musical event of the year” and acknowledged: “these 30 tracks contain plenty to be studied, enjoyed and gradually appreciated more fully in the coming months.” In his review for The New York Times, Nik Cohn considered the album “boring beyond belief” and said that over half of its songs were “profound mediocrities”. In a 1971 column, Robert Christgau of The Village Voice described the album as both “their most consistent and probably their worst”, and referred to its songs as a “pastiche of musical exercises”. Nonetheless, he ranked it as the tenth best album of 1968 in his ballot for Jazz & Pop magazine’s annual critics poll.

The release also coincided with public condemnation of Lennon’s treatment of Cynthia, and of his and Ono’s joint projects, particularly Two Virgins. The British authorities similarly displayed a less tolerant attitude towards the Beatles, when London Drug Squad officers arrested Lennon and Ono in October 1968 for marijuana possession, a charge that Lennon claimed was false.
