Four episodes into season 5, I think this is one of the best seasons yet. They're starting to focus more on teasing us with gradual revelations of the mythological elements of the show's world, and less on character. Considering that there really aren't too many more episodes of the show left, EVER, I guess they really do need to start moving the show forward more quickly. I bet the producers and writers wish they could have a "do-over" on some of the more meandering episodes in season 2, now. For a while, it seemed like nothing happened, and now it seems like fairly major reversals (oh, we have to go BACK to the island now?) have been fairly rushed along.
