If this culminating season doesn't have the same zip - energy, inventiveness and barrelling momentum - as its predecessors, it comes close to making up for it with its dedication to shedding new light on what it means to be good, and to lead a good life, and continuing to excavate from the soil of its fantastic (ie un-real) premise. And, as always when you get this far into a tv show, there's plenty of built-up goodwill to draw on, for the characters and for the show itself. It ends well.
