Saw my TiVo'd season premier of Lost late last night, and my addicition is back in full force. I won't bore you with theories or questions or detailed analysis. I'll just point you to a post from good ol' Keith, full of good questions, and a link to LostEasterEggs, the best site I've found for screen caps and anecdotal goodies (without going over the edge into full-blown psycho stalkerdom).
I'm so confused, and I'm disappointed that this season is likely to be cut short by the writer's strike. However, since the series now has a end date, I'm relieved to know that there will be an end, and most of the answers are coming.
