In one phrase, this film essentially (and also masterfully and gently - yes, gently, despite all that presumed drama on the screen) tells the viewer that all things in life are connected, but nothing really is what it may seem on the surface.
Beware, this is not a comedy, if only somewhat of a comedy Cohen style - at least I can't title it as such. If I define "Burn After Reading" as a dark comedy and social satire, this is rather a philosophical drama sprinkled with (very) dark humor, more of a spiritually charged glimpse at everyday people's reality, and I suspect that as such it may not appeal to a lot of people. Still, fans of Cohen's filmography and people who are interested in spiritual development may greatly enjoy it... I did, very much so.
