I don't mean to be an uber nerd, but I suppose I am...
The Producers have said in a recent podcast, that we should be wondering about where Jack's father's body is. An additional "lead" that is guaranteed to lead nowhere until they choose to reveal what goes on. With a comment like that, all the discussion about future Jack referring to his father upstairs are fair game, including off-the-wall "he is alive" theories.
I think the producers of Lost spend too much time reading the forums and blogs about their god damn show. It feels as if the end of the Season 3 was structured around the frustration everyone was feeling "

ing shut up with your bullshit, and give me some answers instead" (Sun's voice when she spoke with Juliet should have been dubbed with millions of voices of frustrated fans yelling in unison "Some Answers, please?")
As a David Lynch fan myself, I would have been perfectly content if there wouldn't be the Others, and would rather be Losties stranded on an island full of mystery all alone. It would be kind of like watching MYST, and it would never be as popular. As much as I liked this season finale, no other season will ever live up to the calm, subtle buildup and tension of Locke opening the hatch in Season 1. The drama llama is out of the bag, and I'm afraid it will continue throughout. I do miss the carefully planned long executions of simple actions (opening the hatch) that take more than half of the season to realize. In Season 2, the decision to stop pushing the damn button was similar, though much more was going on.
I'm almost pet-peeve-free with the Season finale, with the sole exception of Bernard spilling the beans. Why would a man in love with his wife jeopardize her well being and sell her out to the enemy that has every reason to slaughter them all (in light of them killing 7 others in cold blood)? I'll buy Charlie's death and Jack's whole "I love you" to Kate in light of kissing Juliet.
I knew the show is not going to be MYST: THE HEAD

VERSION as soon as I have reviewed all plot developments revealed in THE LOST EXPERIENCE. Since the producers consider it canon and reveal the mystery of the numbers, I have to say that the answers are dissapointing, but not because they are bad, but because they rid of a spectacularly spooky mystery, and give you no real substance as reward. They are, simply, undoing of the numbers, and undoing of The Dharma Initiative.
Some evil mysteries exist in life to which we wll never ever have the answer for. There is a part of me that is happy that the monster is still a cloud of smoke (literally as well as conceptually), and there is something else to watch out for. However, this is beginning to remind me of The Series of Unfortunate Events book series - setup for a wonderfully mysterious conspiracy theory with no payoff at the end. Most of the things that the characters are after turn out to be McGuffins at the end. LOST is likely to end up the same way, and it would have been perfectly fine, if not for the producers' constant reassurance that "all your answers will be answered."
Having said that, you can all count me in for Season 4 - I don't think this show sucks, and I don't think that it has any value. I'll form my "final" opinion in 2010.
Oh, and this:
[quote name='LinkinPrime']I'm starting to wonder if the show creators, just gave Jack a random obituary, figuring that no one would be able to read it and the name "J.... ..atham" actually wasn't meant to mean anything.[/quote]
Not a chance. Landelof, Abrams, and Lieber are greater nerds than we are. Considering the amount of high-res shots of the newspaper floating around, I give them two thumbs up for delivering an extremely well done "anchor." The newspaper might make you feel that you can solve it, but my their design - you can not. If you had seen the clarity of all the text
apart from the one that matters most in all of the shots, I do have to say that this was masterful on their behalf. Try filming a piece of paper to hide a handful of words that give out what matters most, and you'll see what I mean.
