it really only confirmed what I've been saying for a while now about them clearly having made things up as they went along
...despite always being told and shown otherwise?
Yes, I realize that producers have
claimed they always had the end game in place. And I'm willing to concede that, early on, they decided Jack was going to be dead and not know it. After all, they wanted to kill him in the first ep.
But clearly, because so many fans were guessing answers along the lines of "they're all dead and in purgatory" from the beginning (also, they couldn't very well admit they'd decided to rip off "Life on Mars"), the producers kept throwing in red herrings and issuing denials.
So they tossed in other stuff as they went along that wasn't consistent with either the planned finale or other plot points in the series. Ironically, this resulted in setting up a really good potential "sci fi" style series (and ending).
But, rather than give us that, they really, really, wanted to do the "Jack is Bruce Willis in the Sixth Sense." So they reversed course in the final season, put us back squarely in the "it's magic and they're all dead" category and pretended that everything added up.
Case in point:
1. There was a scene of the Island UNDER WATER at the beginning of season 6. Why would this exist in purgatory?
2. The bomb detonated at the end of season 5. If there was no timesplit, then the actual reality would simply have seen the detonation of the bomb. All characters dead; end of series.
3. Juliet confirms that "it worked" meaning the bomb exploded and an alternate reality was created.
4. Desmond saw bits of the alternate reality. His 'power' was time travel, not seeing dead people. Miles, if anyone, should have been involved if that was the intended ending. In fact, why did Miles have the power and then never have it come into play except for (a) the diamonds; (b) realizing ben killed Jacob?
5. Sayid had a fling with Shannon. He spent his life pining after Nadia. The writers told us over and over she was his true love. Then, in the final season, we're led to be believe it was really Shannon all along?
6. In a similar vein, if being with your true love allows you to remember and pass on, then Rose and Bernard should have been long gone (or at least far more aware of the fact they were dead then we led to believe).
7. Why are there new characters in "heaven" reality? You're not gonna convince me that Jack's kid was just another creation of fantasy, but apparently that's what the show would have us believe: that all the new characters are red herring "filler" for an alternate reality.
