The fact that everyone is thought to be dead, answers the question of why they haven't been found. No one is looking for them. Well, that and the island seems to be hidden pretty well. I didn't think it was gutless at all, though I can see why you might feel that way. As for more questions than answers. They are, after all building to the season finally. That's all about big questions that won't be answered till next season.
