Search: Directed by Morgan Spurlock

It's easy to charm an audience with warm-hearted stuff like this. Where Spurlock really succeeds is in cramming so much meaningful information into his deceptively lightweight film.

The limited time given to each of the short films means that there is little opportunity to get really down and dirty with the number-crunching, so that for every aspect that is fascinating there is an attendant frustration.

But while this documentary may be as carefully constructed as the band, no amount of stage management can stop genuine emotions seeping through, and you're likely to find your cynicism crumbling in the face of the lads' sheer energy and down-to-earth char

Through the use of quirky art work, animation, a barrage of facts and figures, plus an incredibly dry wit, Spurlock shines a light on America's attitudes to weight gain.

Whatever you think of Morgan Spurlock’s incisiveness when it comes to issues, there’s no denying that the man has style.
