Watched Adam Curtis' latest documentary, Bitter Lake, last night.
In summary, it is about how the narrative of 'good vs evil', often perpetuated by western political leaders and the media, no longer makes any sense; it uses Afghanistan as an example of this this.
Really enjoyed it. Whilst it doesn't really provide anything too new or revealing, it does do a great job of tackling what is a very complex topic and presenting it in a coherent and simple way (although Curtis' style can be a bit trippy at times).
I always enjoy his films but I also take them with a pinch of salt; the way he uses stock footage and music, and often without interviews or references, makes him seem more like a glorified conspiracy theorist than an investigative journalist. But Bitter Lake basically summarises the the last 70 years of Afghan history, with facts and claims that can be easily checked/verified; he's not making any bold claims here as he has in his previous films, but instead is just laying out what we all know, in way that is easier to make sense of.
