I wouldn't want to give the impression that the Lighthouse is an easy film to watch, by any means, but it's certainly a worthwhile one nonetheless. It doesn't have a plot, there aren't any characters you can really identify with who develop over the course of the film, and it can often be difficult to follow exactly what is going on, even over the course of a fairly short film where not a great deal happens. But the fact that it doesn't function in the manner of a typical movie drama works in its favour, the film seeking rather to create strong impressions and ideas within the viewer by other means, and consequently The Lighthouse is likely to have an even greater impact on anyone who sees it.
Even if it's not entirely clear where it is set exactly - it's filmed in Armenia, but it could be any remote mountain village in a war-zone in the Caucasus, in Georgia or Chechnya - nothing is clearly laid out in a linear fashion for you to follow and there's little in the way of explanatory dialogue, but you will be surprised just how much you can take in from the way that the film uses impressionistic imagery and stunning cinematography in a way that allows you to piece together at least the essential idea. At the core of the film, there is a young woman who has returned to her home in a remote Russian village, a village populated by mainly older people, the kind reluctant to leave their homes in spite of the signs of conflict that is evident all around them and the military presence in the region.
The sense of location and situation then are clearly presented, but what also comes through strongly is the sense of family and community bonds that exist between the people there, even if there are no conventional dramatic events to spell this out. It's certainly autobiographical to an extent, the filmmaker Maria Saakyan attempting to put personal impressions and feelings up on the screen through a variety of means and often through striking imagery alone, and to a large extent, this succeeds. There's an influence of Tarkovsky here, evidently, and with its military subject and setting, something of Sokurov (particularly Alexandra), but there's something also of Kiarostami in the use of landscapes and the expression of people's lives within it.
If this sounds all rather too vague, the Second Run DVD includes a booklet with essays that provide considerable background detail, analysis and insight onto the film, but you'll be surprised how much you've already taken in from just viewing the film, perhaps without even realising it. The DVD also includes another superb 25 minute short film by the Maria Saakyan, The Farewell, where the same sense of impressionistic detail, fine cinematography and autobiography is used to similar striking effect.
