Sum 41's first album, Half Hour of Power, was not very good, which is why nobody had heard of them back then. All Killer, No Filler was a big improvement but was still quite childish and, despite its title, had too many songs that just frankly weren't good enough. This new album however is a whole lot better. From the music, which is now more metally and mature and has obvious influences from bands such as Metallica and Iron Maiden, to the lyrics which are more interesting and socially aware, this album is a big step in proving that the band can actually play some proper rock music!
Standout tracks are opener "The Hell Song" (incredibly catchy tune), single "Still Waiting" and both of the superb metal-style bonus tracks "Reign in Pain" (cheesy and amusing but still great) and "WWVII Part II" (surprisingly mature).
