It's very good, although I actually agree with a fair amount of what pitchfork said. Basically, it trades in all out power for a touch more refinement and beauty. Having said that, there are a few balls-out, 'batter you round the head with a broken guitar' classic Mogwai moments, its just that they tend to be quite short, which kind of diminishes the catharsis they could be capable of.
I would write more but I'm on a uni pc and the keyboard is driving me nuts!
For me, 4 stars, better than Rock Action and Happy Songs, but not as good as CODY or Young Team.
