I thought it was quite good. Very different from the others, but that's the nature of each season being a different story in a different era. Pretty funny watching Ewan McGregor play both (non-twin) brothers. In some ways it was much more grim than other seasons, maybe due to the modern background problems being so familiar - like the British villain and his fake (albeit amusingly absurd) facts, straightforward greed as a motivator of nearly everyone, political savvy winning over competence, etc. It was also quite different in the surreal elements crossing into the realm of science-fiction and divinity. But it was still emotionally quite powerful. It was possible to identify with the scumbags, and even with the outright villains at times. And nice action scenes with smart plot twists.
