This idea of fate could tie together the show's fixation on free will, birth, life, death, and limitations. I'm hoping the message of the show will involve something along the lines of Locke's faith being the source of his free will. That would be neat.
Wherever they decide to go, I want the end to at least be as cool as what I just described, if not better. If not, I'll be forced to regard this show as a failure. They've backed themselves into too many corners and I don't want them to explain all of that away with simple smoke and mirrors. In fact, if the whispers that Sayid heard in the jungle were simply "the others" hiding in the bushes and if the creepy, silent people of the jungle (which trained the teddy-bear sporting child to be creepy like them) were just "the others" out for a Sunday afternoon stroll, then my respect for this show will have dropped dramatically just from those explanations alone.
