Having listened to the album several times now, I can say it's definitely not their worst album. It's as challenging and surprising as most of their others, but they also seem to be having more fun than they did in Resistance. ‘Supremacy’ kicks things off with a riff straight out of a Bond theme, followed by a more electronic sound than they've had in previous albums, without neglecting their classical roots. The big surprise is ‘Unsustainable’. Never did I expect to hear dubstep (eww!) on a Muse album, but what's perhaps more surprising is that I really like it. Amazing album.
