Just as I Am met with generally positive reception from music critics. At AllMusic, Stephen Thomas Erlewine rated the album four stars out of five, writing that Gilbert is "an outlaw with no desire to rebel, an insider who doesn't belong, so his music exists just outside of the perimeters of what is accepted and is all the more powerful for it."Brian Mansfield of USA Today rated the album two stars out of four, stating that " Coupling '80s-rock machismo with backroads buzzwords, these songs play like set-list padding." At Country Weekly, Tammy Ragusa graded the album an A, calling this "a much more mature album and the exact collection he needed to secure his place in the history and future of country music." Markos Papadatos of Digital Journal rated the album four-and-a-half stars out of five, remarking how on a release that shows his further refinement "as a vocalist and as a songwriter", Gilbert makes it clear on a musical project where "nothing [is] fake about him and there are no apologies on this record." At The New York Times, Jon Caramanica gave a positive review of the album, saying that Gilbert "is a lunk with poet dreams, a bodybuilder cradling a newborn" because he "certainly [has] an intimate understanding of how his hard exterior allows him to flaunt softness when it's called for." Matt Bjorke of Roughstock rated the album three-and-a-half stars out of five, indicating how this "is a confident, well-made album with much of what has made Brantley Gilbert the big rising star that he is and will keep his massive fan base completely happy."
