In "Mojo"s "The Beatles' Final Years Special Edition" (2003), Peter Doggett acknowledged the comparative rarity of "It's All Too Much" within the Beatles canon and added: "Yet it's one of the pinnacles of British acid-rock, its sleepwalking rhythm retaining a bizarrely contemporary feel today." Having included the track in his 2011 list of Harrison's "10 Greatest Beatles Songs", Joe Bosso of MusicRadar commented: "At times the song seems to drift away with Harrison's dreamy verses, but just as quickly it's chopping down trees with explosive percussion and thunderous handclaps. Wild guitar breaks by both Harrison and John Lennon help to make It's All Too Much a dizzying treat."
