Lost seems to revel in breaking its characters into seperate tribes around season finale time and this year, it is no exception. The lostaways have different motivations, different wants, and all of them are striving for seperate and increasingly incompatable goals that can only bring them into conflict with each other. The drama is nom-nom-nommy.
It's difficult to really take in what a rich tapestry of characters that this show has woven over the last four years. From the coniving and bitter Ben, to the mysterious Locke, the desperate Jack... all of them seem to be coming together quite nicely for the coming finale.
Even the newer characters like Elouise are quickly becoming favorites as they jockey for their own positions in the Lostiverse.
With tension this high and without an easy way out of the predicament that is brewing, the real question is "where do we go from here?" Given how entertainingly that Lost has gone off the rails this season with the time travel element, the answer is an unequivocal, "Anywhere!" and that is what makes this show so entertaining.
