I'd only watched a few episodes of the first season and didn't care for it. Too confusing. However, when I Read about it tonight, from what I understand, is the island was real and they did die in the crash. Said that in the first episode you see Jack open his eyes and then the last one you see him close his eye. Soooo it took six seasons for him to die?
I'm still pretty confused, too.
