I'm pretty sure I've already mentioned this, but I've come up with an explanation for everything that's happened in Lost. I think the whole story makes a lot of sense with it, with the exception of the time travel mechanics (which almost never make sense in
any story). I also think it's very plausible that everything I've come up with is the original intent of the writers, and that by the end of the show much of it could be explained in a straightforward way.
If you want to see what I've come up with, I wrote it all up
here.
Now, I'm not saying that I'm necessarily right. It could be that I've misread all the clues and the actual explanation is going to be something very different. But what my theory proves definitively is that it's
not too tangled up for it to all make sense somehow.
