 Reviewer Chris Carabott of IGN rated the episode with an 8.7 out of 10, commenting that "One of Us" was "yet another solid effort from long-time Lost director Jack Bender who deserves credit for bringing us some of the best episodes the series has to offer. Bender has helmed" Walkabout "," Man of Science, Man of Faith "and this season's best" The Man from Tallahassee "just to name a few". BuddyTV senior writer Jon Lachonis commented that "One of Us" was "perhaps the most perfect episode of Lost ever produced, bar none. For those of you who were upset with how inelegantly" Exposé "squandered its flashback opportunities, prepare for a huge apology from the producers. For those Lost fans who stuck around knowing that the show would obtain that mythical level of greatness that seemed to come so natural, here is your pay-off." In this same review, he complimented Elizabeth Mitchell on her portrayal of Juliet.
