The album has received generally many favorable reviews from the critics. Corey Apar of Allmusic awarded the album 3 stars out of 5, stating "Overall, The Poison is a well-produced, solid effort — but seeing as they're now trying to take over American hearts, it would be nice to see future attempts to distinguish themselves more from the new-school pack."Sputnikmusic also gives the album a 3 out of 5 with the explanation that it's "fun to listen to, and the guitar work sure is nice. The vocals are good as well, as main singer has a good voice, melodic and screamed, well supported by the screaming of the bassist."
