Well, I've just finished watching the entire Season 3 on DVD, and it was
intense. George is probably going to disagree with me on this, but...I don't know how much more I can take

. The end of Season 3 has
flash-forwards (yes, we're going post-island now) and features a very unhappy and intoxicated Jack attempting suicide. Obviously the island has become an opium to him, and now (as he tells Kate) he wishes he could return to it...
I really wish J.J. Abrams would tie up
all the loose ends in Season 4 and be done with it. This is beginning to be a really long-haul watch...guess I'm not a 100% Lostie
