It's the rare film that gets its value upon reflection rather than during watching. It's not boring as such, but with its extremely long runtime it does generally feel slow paced and often runs the risk of being quite dull. Luckily though, the pure sense of mystery that surrounds the three core players (our protagonist included) and the film's world as a whole keeps things intriguing throughout. As the narrative progresses, however, and the core mystery of the piece arrives, things get a lot more intriguing and this intrigue lasts long after the haunting finale. That's where the film really gets its merit. None of the enigmas are definitively answered, and this leads to an extremely subtle - yet wholly rewarding - experience that allows you to draw your own conclusions of what it was actually about. The picture could be about several different things, and it all depends on the individual spectator response. This, as well as the complete lack of on-the-nose exposition, is very refreshing in today's age of cinema where nothing is left to the imagination anymore. We are not told, or even explicitly shown, anything integral to answer the core mystery and this allows you to reflect on all of the intricacies of several different scenes in order to draw your own conclusions. It really is a one of a kind experience that will leave you scrutinising for days, discovering a new narrative possibility upon every thought. Its slow pace and the sense that it's not really going anywhere might make it seem hard to get through initially, but once it's over it becomes a rich, rewarding experience. 8/10
