It Might Get Loud

The mood's too good-spirited, and in that there are great pleasures - not least the sound-of-mind thinking of three rockers putting paid to the tired cliché of burbling rock gods trapped in their own shadows.

The film might have benefited from a trim and a more linear approach, but mostly it fulfils its role as an illuminating homage to both the protagonists involved and, above all, the guitar as popular music's most timeless icon.

As the summit of strum builds toward the inevitable guitar showdown, it's easy to feel a little let down as all that promised head-banging volume instead goes out more like a whimper.
