I too found last night's finale to be quite enjoyable. The focus of the show will definately shift from this point out. Up until now the point has been to: 1) survive and 2) try and find a way to get off the island. They've succeded in those two things. I'm not so sure that we know where the next focus is going to be. For all we know, the first episode of next season could be them being rescued (not probable, but it's possible). What I appreciate, for the most part, about the show is the tension that comes with not having answers provided so darn quickly. I think that is intentional: the uncertainty we feel as viewers is akin to similar feelings of the castaways. The show lives in the grey area of questions instead of plowing straight through to black and white answers. I certainly agree that Ben and Locke's attemtps at convincing Jack and the castaways not to use the phone/get off the island was weak. It seems to me that a fair chunk of the remaining three seasons will have to deal with the question of why the island is special. As viewers, we've been wondering that for quite some time, but for the characters in the show, that's taken a back seat to their desire to get off the island (which is pretty reasonable). So far, the unique qualities of the island are only important to the people who have experienced them in a profound way, particularly, Locke, Ben, and the Others. I think that as the characters get off the island, that question will become more important for them as they deal with those questions and therefore become more central to the plot. The question of who is in the coffin is a good one. I've got some guesses, but really no sound idea. For all we really know, it could be a character we haven't been introduced to yet.
