Personally I like it a lot more than 2nd Law (which I've only managed to get through twice). It's not a patch on Black Holes and Revelations or Absolution but a step in the right direction. I think my favourite song is Psycho because it's so darn catchy, but I also love Mercy, Defector and Dead Inside. It does get a little self indulgent at the end but it wouldn't be a Muse album without that!
Wish I'd managed to get tickets for the Psycho tour, think it would have been epic.
