Paste critic Jeff Elbel described the release as "an appealing but inessential curio," writing: "Given the steep asking price for this Japanese import, I’d spare your wallet the needless emptying."  Allmusic 's Andy Kellman thought: "Naturally, the release isn't nearly as cohesive as Hail to the Thief ; its apparent intent is to supply the fans with another stream of the band's recordings, regardless of both how they fit together and how mixed the tracks are to begin with."  Chris Ott of Pitchfork criticized the EP, writing: "You'd expect more from ideas that Radiohead fleshed out as a unit, but the stolen-time experiments and solo performances on this EP's tail end far outshine its exhausting first half." Ott also stated that the release is "worthwhile only to Radiohead's wealthiest fans." 
Yorke also took phrases from Dante's Inferno , the subject of his partner Rachel Owen 's PhD thesis.  Several songs, such as "2 + 2 = 5", "Sit Down Stand Up", and "Sail to the Moon", reference Christian versions of good and evil and heaven and hell , a first for Radiohead's music.  Other songs reference science fiction and horror , such as the wolves and vampires of "A Wolf at the Door" and "We Suck Young Blood", the reference to the 1949 dystopian novel Nineteen Eighty-Four in "2 + 2 = 5", and the allusion to the giant of Gulliver's Travels (1726) in "Go to Sleep".
