Critical reception

Oggs Cruz of Rappler gave a mixed review, calling it "a beautiful film" but also "dull and ineffective" and that it "feels too mechanical, too designed to work." Yet he complimented the "overflowing" musical score.^[15] Philbert Ortiz Dy of ClickTheCity.com rated the film 2 out of 5 stars, saying "the [film] is just oddly constructed all around. There’s just so much to address, and the movie just doesn’t seem willing to do the work to give all these issues the time they need."^[16] Nazamel Tabares, a movie blogger for Movies Philippines, also rated the film 2 stars out of 5, saying that "there’s nothing new in the film and nothing worth keeping after seeing."^[17] Je C.C. of Philippine Entertainment Portal said of the film, "Still falling into the pitfalls of Star Cinema cliches, Barcelona: A Love Untold becomes a film of blemished beauty, but that is fine."^[18] On the other hand, Rod Magaru, an entertainment blogger, rated the film 9 out of 10 and called it a "masterpiece of 2016." He commended Carmi Raymundo for the way she wrote the flashbacks and added that "it is one of her best."^[19] Edmund Silvestre, New York correspondent for Philstar Global Entertainment wrote, "Barcelona is an enchanting (and hit) tearjerker."^[20]
