Subtle, dense and slow. From the length to the technical mastery, it is a masterpiece. For me, the scenes of deep discussion didn't work as well as those of raw emotion. That is, Andrei and Theophanes talking about human nature is nowhere as strong enough as The Feast or The Raid. But overall it's a great and subtle film that definitely requires more than one viewing, even if at over 3 hours long, it's not that easy.
