Miniseries + four seasons. Very good, and each season better than the last - once it got going, it really made me want to find out what would happen next and how things would end. Reminded me a bit of Lost - not least in its more metaphysical tendencies - although more tightly plotted. And its focus on choices and their consequences, and the moral elements of the decisions made by all of its major characters is effective, as is (with some caveats re: occasional lack of sophistication) its staging of classic societal and political issues in its sci-fi context of a beleaguered last 50,000 survivors of the human race fleeing their robot antagonist through space in a giant fleet. I wouldn't say this was a truly great show - it's no West Wing, say - but it was plenty enjoyable.
