"In the Morning" received mixed reviews from music critics who found it reminiscent of Up All Night but were put off by Johnny Borrell's performance. Paul Stokes of NME praised the song's instrumentation and lyricism for its depiction of a hangover after a big party, saying that it "sets the tone for Razorlight to sound like the classic rock’n’roll band they always imagined in their heads: bigger, bolder, brighter." Noel Murray of The A.V.
