This album isn't half as bad as this website is making it seem.
Don't Blink is super good. Can't Complain is good. And Collapsible Lung is good. They're as good as any of the bands classics, particularly Don't Blink.
That being said I think people are all over this album because it also features 3 of the worst songs Relient K has ever released, IMO: Lost Boy, PTL, and Disaster.
Overall, although it's not their best work, it's still far better than your average pop release these days.
"Gloria" is worse than all three of those songs combined IMO.
