Is it a war movie? Is it film noir? Is it cheap titillation? A deep exploration of complex and controversial relationships? This film cannot decide what it is and so, as another person noted, must require several viewings in order to make sense. Sadly, it is just not compelling enough to warrant multiple viewings - unlike other films that ARE rich with complex themes and artistic vision.
The actors valiantly try to overcome the morass that is the script - but were probably as annoyed as the rest of us at the myriad loose threads that never tie up.
Adrian Dunbar portrays the frustration of someone tempted and confused by things around him - he must be the avatar for the viewer. Stephen Dorff offers another workmanlike portrayal of your friendly neighborhood rebel without a clue. Gabrielle Anwar, who is usually a fine actor, is stuck with a character whose neuroses become tedious and irritating by the end of the film. Joanna Lumley escapes caricature by a false eyelash and looks luminous in the period fashions. The rest of the cast are superfluous at best and annoying distractions at worst, doing nothing to advance the story. They and the plot lines that involve them do not even qualify as decent red herrings.
The cinematography is lovely - very atmospheric and evocative of the era - as are the costumes and staging.
Unfortunately, Dewolf's grasp at Art exceeded his reach and no amount of plot devices can make this murky movie anything more than a mild diversion. Perhaps the fault lies with the editing - which would explain the subplots that disappear and other senseless oddities. A tighter script, a focused plot, and less cheap titillation would have permitted this talented cast to fully engage the viewer in a riveting mystery flick.
