AllMusic editor Roxanne Blanford wrote that the song is "gentle", arranged as a "pseudo-procession tune", "as if Emilia is taking her first cautious steps toward independence and adulthood."^[4] Chuck Taylor from Billboard said that its "magic touch" is "manifested via sheer straightforward simplicity-in performance, production, and message." He noted Emilia's "delicate voice, ripe with vulnerability and hurt, tells of being a big girl in a big world who shouldn't see it as a big deal if her partner leaves her ... but she will miss him much." He also added that "allusions to rain and autumn leaves help set up a perfect visual of stark sadness and loneliness, giving the song a strong seasonal punch."^[5] A reviewer from Birmingham Evening Mail stated that "this is another one of those Love It or Hate It records", adding that "its incessant beat and simple rhythm will either drive you mad or drive you to put it on the CD player again...and again."^[6]

Daily Record called the song "chirpy".^[7] Swedish newspaper Expressen wrote that "Big Big World" is the "big, obvious hit this fall."^[8] Göteborgsposten commented that with this song, Emilia "has a big, big hit".^[9] Chuck Campbell from Knoxville News Sentinel said that the 20-year-old vocalist "assumes a sweetly fragile persona on the song, setting the mood with a sparse verse and chorus before the track folds in a shuffling beat and an orchestral arrangement."^[10] Nina Cassidy from Stanford Daily noted that it "has a catchy beat, and the lyrics and music have a smooth flow."^[11] Sunday Tribune called it a "sweet song",^[12] while Sunday World described it as a "cracking single".^[13] Kerry Gold from The Vancouver Sun deemed it "a song of such easy listening it could double as a nursery rhyme."^[14]
