well, let me answer the obvious, YESSS i do, but this is not what i am talking about. You see, part of LOST's intrigue is IN its secrets and mysteries. take that away (by revealing all) and the show will normal again.
think about it, it's like a magic trick, once the trick is revealed, then it loses its "Wow" effect. As for a LOST example: i remember in season 4 seeing Richard watching after young John Locke's and actually meeting him, i remeber i was blown away with intrigue. but as soon as i saw in season 5 that that was simply because JL came back in time to told Richard about his birth date, etc... and i was like ... hmm oh, ok.
so what i meant is, do you really want EVERYTHING to be revealed? or do you prefer so stuff remain a mystery ???
