i think they basically make up shit as they go along, i gave up watching after a black cloud came into things, and then he had to go and kill the black guy, i really liked him.
Its like they throw darts at a dart board with ideas on paper stuck on, see kids, despite the Myths, drugs dont improve story telling.
The Lost team keep dropping hints to some relevent story line but its utter crap, they'll just try and tie it together as best they can with Duck tape, what is with the island, is it a research centre mystic island, heaven, or the gateway to heaven? make up your fucking minds.
though i have to admit its so utterly confussing you feel like you have to watch it so you get that "OOOOOHHHHHH OF COURSE!" feeling before you flick the channel to babe watch or will and grace.
