The U2 mystery has gone. Apart from being a quartet of forty-something blokes with the same trademark guitars and an immense back catalogue, their purpose seems unclear.Unfortunately, this dull album shows this lack of purpose to have reached crippling levels. At times it's as if as the band, lost as to their true identity, start playing what they think U2 should be playing. It sounds so familiar. No substance at all. It's just marketing, fashion, Grammy Awards, etc. The album quickly descends into an uninspiring mid-tempo plod.The overall impression is that they've forgotten about the songs and preoccupied themselves worrying about the textures. Stuck between second-guessing their audience's expectations and where they actual want to travel, they end up in a cul-de-sac of their own making.Stuck In A Moment They Don't Want To Get Out Of.
