I have't geeked out this season about LOST... you are either into it, or you suck. Whoops, I meant to say, you are either into it, or you're not.
This season is interesting, as the cast dynamic has shifted alot, and the writers are addressing questions that directly confront why the island is a source of phenomena. At the end of the day, the payoff requires that the meta-narrative acknowledges that the island is somehow conforming to different rules of physics. Otherwise, it just doesn't matter.
If you aren't sold on Lost, netflix the first season. If you sit through 3 episodes (roughly the length of an average movie) and still aren't convinced, then its time to move on.
