The album was generally received negatively among professional reviewers. Rolling Stone attributes the album's failure to a change in the group's style, calling the album "a poor man's Goo Goo Dolls". Allmusic claims, "O.A.R. wasn't designed for Top 40 radio, which makes All Sides...disappointing."
The album however is the band's highest charting album to date, debuting at #13 on the Billboard 200 with approximately 33,000 copies sold in its first week. It has become O.A.R's second best selling album in the united states, selling over 700,000.
