I think it's a little richer than just seeing "a bunch of dead folks," don't you think? Strangely enough, I am much more inclined now to see it as a kind false utopia, a true temptation, much like the "mirror" life Christ lives in The Last Temptation of Christ: he is given everything he thinks he wants, he is allowed to have a life experiment, and only by placing himself in this radically different existence does he come to see who he is and what he is meant to do. Season six has been a slow burn of this kind of experiment -- Desmond could have resisted the urge to see the truth, and immersed himself, as Eloise suggests, in what the Mirror had offered him, in fact, what he had constructed for himself. If we take Christian literally, then the Losties tested themselves, put themselves in another life, with new relationships, different outcomes, experiences and memories, all to see if the truth, their true selves, would come out in the end. That was the struggle of season six. Jack resisted it most of all. Surely, his own construction, what he unconsciously gave himself, was the hardest to let go -- his son. If he, and the rest of them, triumphed, it is because they were able to see the Mirror for what it was, a mirror, a reflection, not reality, and moving from that reflection was letting go of their desires, and achieving transcendence. That's what it seemed like to me, anyway. It felt like, in that time-less "moment" of the Mirror, they were able to really accept death itself. It wasn't just something forced upon them, but something they could freely embrace. You could ask whether this was real, or a kind of rationalization for something beyond their control, a kind of faint dream in Jack's dying brain, as the veil of death is slowly laid over him. It's a very rich and provocative solution that leaves many roads open to question and interpretation.
