Advertisements I'm with Rob on this. Emotionally, and from the character development viewpoint, this was very satisfying conclusion. But in this context, the entire flash sideways scenes as a whole are little more than a very good reunion episode. Except for Hugo and Ben's throwaway lines, there was nothing that advanced the island mythology (and I await the fan drawing or photochop of them as Mr. Roarke and Tattoo). Nothing in the storylines of the flash sideways had anything to do with the mythology of the island, except, ooh, weren't those good times? Hundreds, maybe thousands, of people died over the six years of this show, so I guess that there's a heaven, or whatever the light in the church was, makes it OK. Our favorite characters have a happy ending, and that's what counts. From the intellectual viewpoint, I really hoped the flash sideways would have a more interesting resolution. I was entertained by the possibility they might have been a result of the nuclear explosion interacting with the island's E/M force, that they were a result of some entanglement with a parallel universe that would resolve itself with lots of drama, but no, we get a well tread supernatural revelation. As I said, it was well done, and I enjoyed it for what it was, but as a hard core sci-fi guy (and I know hard core guys don't like the term), it had the potential to have been so much better.
