If you don't like the alternate timeline, what do you think about the story if you forget about that arc and just think of the original timeline and it's finale?
Basically Lost was a very simple story told in a very convoluted and obfuscated manner. Swiss cheese story telling. This was done deliberately and skilfully, bit like a weird multi part viral internet ad campaign... except the final product was never revealed.
Without knowing anything about the island, except that it is real and somehow manages the balance of good and bad in the world, the rest of the story lacks any real substance.
Didn't need a scientific dissertation on the island, but some sort of vaguely plausible explanation would have sufficed.
Of course the writers made up the "magical" island properties for all sorts of deus ex machina throughout the 6 seasons probably knowing full well it wouldn't have to make sense because what the island was (even in its most basic form) was never going to be revealed.
