The album overall gained mixed reviews. Matt Bjorke of Roughstock gave the album a favorable review. Similar to his later review of the single "Summer Nights,", Bjorke commented that the album would appeal to fans of Rascal Flatts, but would unlikely bring new fans to the group. He specifically cited "Why" as the best track of the album, writing, "This is the kind of song that got me to personally like Rascal Flatts and it's certainly the best track on Unstoppable and "There's gotta be 'Song of the Year' accolades somewhere down the line for this song as it's that powerful."[4]
