I gave it a 10.
I read the entire "Didn't Like It" thread and much of the whining and ranting left me shaking my head. As if those who complain of horrendous writing could do any better, really? Truly?
So what makes it a 10 for me?
We were finally given the big story. Jacob versus ???. Those that think the loophole was simply get someone else to wield the knife, I think, are oversimplifying things. I'm sure there's much more to it than that.
While some find Juliet and Kate's changing their minds to be unbelievable, I found it thoroughly believable. Especially Juliet. I think she switched sides because she, a doctor, saw that as a way to save not only the man she loves, but the most people they could possibly save if the plan worked. It was a very selfless sacrifice that she would have to know would doom her to being Ben's obsession.
We finally got to see why these people in particular survived the initial plan crash - Jacob touched them - he has a purpose for them.
Rose and Bernard were the voices of sanity during an insane time. I believe they are meant to show the Losties where their hearts should be and exemplify the type of people Jacob has been trying to bring to the island to prove ??? wrong.
Miles - I loved when he pointed out that they were likely fulfilling some kind of Greek tragedy by causing events that they were trying to prevent. Bravo.
Hurley - a truly good soul - the only one Jacob gave the choice to as to whether or not he'd return. And I believe that his making it Hugo's choice rather than using coercion is what made Hurley get on that plane.
Poor Sayid. His interaction with Jacob has to make me wonder if Jacob is the good guy after all. Jacob basically caused the conditions which caused Nadia's death. He also enabled Sawyer to write that letter. Makes me wonder if the negative LOST screen at the end is indicative that those "black" characters are the good guys while those wearing the white hats are the bad guys.
And this particular cliff hanger leaves much to debate over the long months ahead.
