Due to time constraints, I won't go into a lot of detail about the season premier of LOST other than to say IT ROCKS.
The best part?
Finding out who (or what) the smoke monster really is and the explanation for the ash that was always around Jacob's cabin.
The biggest challenge the show will have this season is the end game. If they can leave viewers satisfied after they close the show, then this would have been a six year journey worth taking.
