This was on the pile forever, probably as a jag from Winterbottom's excellent Jude, which I should have rewatched in preference to this dreck. A quick look at IMDB suggests he has been running out of ideas for a long time now. In essence this is an episodic snapshot of the British indie music scene circa 2004 intercut with some hardcore sex that perhaps just maybe is supposed to provide characters and propel a plot. Really there's no arc and it's entirely vacuous. The Antarctic thread was absolutely spurious. As someone may have said, it's a continent in search of a penguin.
Roger Ebert is obviously sympathetic to sexy movies but could only manage two stars. Damn straight the concert scenes are the most soulless footage ever shot of that stuff. He misses the cue early on from the woman, that she's not there for the long haul. Stephanie Zacharek got into it.
