What was this actually about?
Call me dumb, but my impression after finishing the series was that it was absolutely pointless and gratuitous. A bunch of stuff happens, but no overall meaning, lesson, or even theme can be derived. It seemed to be going somewhere for the first half of the series - I thought it was attempting to line up a series of sociopaths on a conflicting course that would result in... something. But it resulted in nothing.
Or am I looking at puddle of puke trying to find meaning in it?
