Sal Cinquemani of "Slant Magazine" named it "a mixed bag: part retro dance-pop, part prescription R&B, and part Latin", noting that her voice "seems best suited for dance-pop rather than R&B and, judging from this album, it's where her heart is too." In a more mixed review, "Entertainment Weekly"s Tom Sinclair wrote that Lopez "seems lost amid the cluttered, high-gloss arrangements", but stated that she "deserved props" for the album's Spanish language songs. Jon Pareles of "Rolling Stone" was also mixed, stating, "most of the music sounds like jigsaw puzzles: showers of tiny bits and pieces that interlock as complex, coherent songs." Jake Barnes of Yahoo! Music noted that Lopez "mostly sticks to a successful formula - R&B lite with a Latin touch, but said, "are great tunes in the way of, say, TLC's 'Waterfalls' but the Bronx born Lopez's enormous fanbase is sure to propel them into the top of the charts." "NME" Christian Ward, on the other hand, was negative, calling it "a calculated assault on our post-Destiny's Child sensibilities, an hysterical but fatally flawed attempt to prove that this Lopez puppet can do anything her producers ask of her". Josh Freedom du Lac of "Wall of Sound" criticized it for sounding to identical to her debut album, claiming that it "stick[s to the same set of sonic templates throughout the 15-track album, never making much effort to shift up the tempos, melodies, and structures", while Mike Ross of Canoe.ca was highly critical, comparing the music to cotton candy, "made from air, sugar and artificial color".
