I wasn't really sure what to expect from this movie but since this one was included in the '1001 Movies You Must See Before You Die' list, I was quite eager to check it out. First of all, it is obvious that you can't really analyse this movie as a straightforward story as the concept was rather preposterous. I mean, let's assume that this village would really need to dig the sand to survive, it would be much easier and efficient to send some of the local villagers every 3 months willingly going down there for a specific period of time instead of kidnapping some poor random guy. Eventually, it was a very subtle parable but did I really get what the director wanted to tell us? I'm not so sure as I might not be smart enough. As far as I was concerned, I saw it as a psychological thriller with some erotic undertones. Furthermore, I think it was about the fact that, in order to survive, we all need a purpose, even if almost everything we do might seem pointless and we might as well dig endlessly in the sand. To conclude, even if I'm not sure if I fully understood this movie, it was still a really interesting watch and it is definitely worth a look, especially if you like the genre.
