I saw it yesterday, hoping for filmmaker-porn (stuff that gets filmmakers off, but nobody else cares about).
I found the "single-take" conceit to be a hindrance, definitely not adding anything to the story.
Plus, the execution just wasn't all that impressive. Ten-minute takes aren't all that difficult, if you only have two actors, are confined to a small space, and don't care too much about lighting. Try something a little closer to "Children of Men", then you can start bragging.
And yes, they definitely shot this in a series of cleverly-edited shorter takes, made to look like one REALLY long one.
Lau and Kentis seem to have a knack for finding clever ways to make really low-budget movies that attract an audience. Can't say I'm a big fan of their films, though. What's their next gimmick?
