The magazine had this to say:
In the six songs, Green Day keep their punk urgency and lyrical angst, but expand their ambition. They use dramatic musical shifts reminiscent of Queen, and Who-like classic rock guitars. There's even a poignant piano ballad that Fiona Apple could love.
Billie Joe Armstrong's vocals push towards falsetto, adding a new level of emotion to his singing. And his lyrics mix the political with the social, depicting marginal characters betrayed by church and state. Focusing on greed, corrupted religion, and war, the conceptual album is broken into three parts: Heroes and Cons, Charlatans and Saints, and Horseshoes and Handgrenades.
