Sebastian Geoffroy:

I left the film perplexed, but after some thought I have an interpretation.

The film is a recognition that for most of the West, the story is about the individual, their actions, their decisions. However – for many in the non-Western world – the story is about things outside of their agency. The characters discover this in their journey, and the lack of character development is intentional – this is not about them, it is about the context of their life, where much is simply out of their control. The minefield is a pinnacle of this; who lives, who dies – totally random. Heck, even ending up in the minefield was random.

The ending scene is alluding to this – showing the cast amongst migrants, alluding to their recognition that they too have entered the stochastic nature of life. This probably leads to some frustration among Western viewers; they are looking for the individual story. Instead, this is a film about context, and those things out of our control.

As you like to say, context is that which is scarce.

Interested in your thoughts.

I would add two points.  First, I think the film is suggesting that humanity as a whole is making the same mistakes these characters are.  Pointless quests (the daughter is not really missing), recklessness, plans devoid of meaning, and excess attachment to various drugs.  WWIII is going on in the background, on the radio, and in this film the group ends up with the African goat herders, not doing better than they are and also difficult to distinguish from them at first.

Second, many points in the plot parallel episodes from the Bible and the Quran, except the characters do not experience them with meaning.  Abraham offers to sacrifice his son for God, but here the father loses his son for no reason whatsoever.  There are hallucinations in the desert, forty days and forty nights of wandering, Job-like episodes, and more.  Instead of suicide bombers, we have people who blow up randomly for no good reason at all.

Again, this movie would make little sense over streaming.  Here is my earlier review.  Here is commentary from the director in Spanish, I have not yet listened.  Here is a short post on the holiness of the movie.
