Lost Season 5 Finale - What Did You Think?

I'm on the west cost so I've yet to see the Season five finale of Lost. But I thought I'd start a talkback post for all those people on the east coast to get the party started. What did you think? How do you think the story will continue next season? What is your theory? What did you like? What did you hate? Spoilers welcome, of course. Leave your thoughts in the comments below.
