Honestly, there's nothing to say here. If you're a screaming, 13-year-old fangirl of this highly manufactured British boy band, you'll be there to watch this documentary-cum-concert film. Probably in 3D. If not, you can sit back with the rest of us and wonder why the hell Morgan Spurlock (Super Size Me, Where in the World Is Osama Bin Laden?) agreed to direct such an insipid, patently hagiographic effort. Boatloads of money? Simon Cowell pointing a Glock at his head?92 minutes PG.
