Even with a pop music-obsessed 7-year-old in the house I'd managed to resist, or block out, the charm of One Direction. Presented on the big screen in loud, slick 3D they're a little harder to ignore and, to my surprise, even harder to dislike.
I now know what every teenage girl in the world is already across. Liam, Louis, Harry, Zayn and Niall are lovely working-class lads who tried out unsuccessfully as individual singers on Britain's 2010 X- Factor, but were then asked to continue in the competition as a boy band by judge and producer Simon Cowell. They've gone on to make music history by being No1 in 37 countries and are nothing short of a phenomenon - it's a remarkable story for a boy band who can't really dance.
For a man who mostly likes to make films about himself, either eating McDonald's (Super Size Me) or trying to fund a movie through advertising (The Greatest Movie Ever Sold), director Morgan Spurlock keeps out of shot. A more conventional documentary, this is a behind-the-scenes tour loaded with plenty of concert footage, interviews and screaming fans.
He's managed a few Spurlock quirks, though. A neurologist is included in a comical piece explaining how the brain works and why One Direction fans aren't "crazy", just "excited", and there's use of eye-popping graphics over live concert footage, which makes the numerous musical performances more interesting.
Mostly though, it's a backstage look at the gruelling schedule of a world tour, while also showing the boys being idiots and following them home for a little soul searching.
