This is a very eerie, striking and meticulously crafted piece of cinema. Several themes presented at the start are thoroughly explored. For example, cellphone footage of Saddam Hussein's hanging relates to cellphone recording of a fight between two girls posted online that Robert watches and also cellphone recording of the tragedy. Expectations are constantly undermined: vocal sounds we assume are of pain turn out to be a baby playing; online footage (blocked from view by the back of Robert's head) turns out to be not what we imagined.
The use of the widescreen format is superb. Heads are lopped off, actors are confined to the periphery, an important sex scene takes place just out of shot. The tragedy itself is brilliantly depicted, distantly, through the viewpoint of Robert's static camera, which makes it all the more chilling.
Yes. it's all very clever and cerbral, detached and a tad surreal in mood, but it's also immensely watchable. And you'll be reflecting on it long after you've ejected it from the DVD player.
