Only One Road

Larry Flick from Billboard described "Only One Road" as "another glistening pop ballad" from Dion's "memorable" album, The Colour of My Love. He noted "her flawless soprano range [that] flexes admirably within this infectious and appropriately dramatic composition. It is difficult to imagine any pop or AC programmer with a penchant for gooey romance not putting this on the air instantly. Just lovely".^[1] Pip Ellwood-Hughes from Entertainment Focus called it "one of the album's finest moments", describing it as a classic ballad with "one of the best vocals on the record". He added that Dion's "power, strength and control" make the performance sound effortless.^[2]

Dennis Hunt from the LA Times compared Dion to singers such as Mariah Carey and Whitney Houston, pointing to "that grandiose, note-stretching finish" on the track.^[3] Pan-European magazine Music & Media wrote, "Think twice before you drop this one. But it's fair to say now that La Dion has become the 1990's Streisand, for whom singing big ballads was like brushing her teeth".^[4] Music Week awarded the single three out of five, stating, "How do you follow 'Think Twice'? With another show-stopping ballad, of course". The review added that the release "keeps up the Canadian songbird's profile and should whizz off those racks".^[5]

Jordan Paramor from Smash Hits also gave "Only One Road" three out of five, calling it "dead romantic" and praising Dion's vocal performance.^[6] Annika Heinle from The Stanford Daily described the song as a "tearjerker", writing that "it's all about memories, standing tall and Celine Dion's diva stage moves".^[7] Christopher Smith from TalkAboutPopMusic called it a "more restrained number, slower paced and more soulful", adding that it gives Dion "the chance to stretch her lungs over each and every chorus".^[8]
