The album was met with mixed reviews by music critics. Timothy Powell of the BBC stated that the album "reveals a band that is fresh, vital and ferociously good." He went on to say that the Script are now positioned as "next big thing" and that the album entails "hip-hop, pop melodiousness, state-of-the-art production and anthemic rock." His overall summary was that the album is "Intelligent, beautifully crafted and compelling." Nick Levine of Digital Spy gave the album 3/5 stars while saying it was often "devastatingly effective" and that "A lot of people are going to hate the Script, a lot of people are going to love the Script."
The German WOM magazin monthly went as far as writing: "Eigenständing und originell ist anders. The Script bringen die Misere der Musikindustrie auf den Punkt. (Independent and original [music] is different. The Script points out the music industry's demise.)" The album has mixed reviews in MTV Asia, which has praised "O'Donoghue's vocals are a pleasurably unique aural experience" though it also comments that, as a whole, "the album plays across a flat plane, with no big leaps, but no huge letdowns either."AllMusic's Alexey Eremenko said that the album was "not reckless or fuzzy enough [to be] power pop"; instead the closest discernible influence was the rock style of U2.
