 At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, Mi Reflejo received an average score of 56, based on seven reviews, indicating "mixed or average reviews". Stephen Erlewine of Allmusic described the album as a mirror image of her debut album Christina Aguilera. He felt that it was a "little too familiar" although he praised recordings as "well-produced"; however, he concluded that the album "doesn 't add anything new to her music, since it's just the old music in new clothing." An editor for Billboard wrote that Aguilera has yielded a mostly mainstream pop album with Latin inflections. Eliseo Cardona of CDNow gave the album a mixed review. While he enjoyed Aguilera's vocal performance, which he described as "precisely, gracefully, forcefully", he criticized the literal Spanish translation of the lyrics from English which he said made a "good laugh and a better yawn". He commended "Cuando No es Contigo" as making Aguilera a "credible, expressive salsera" and her cover of "Contigo en la Distancia" as the album's finest moment.
