I'm asking how people didn't see it coming.
Because the show has never been this bad or disrespected its audience to this degree. That's how!

Well, I have been suspecting for quite some time that this was the logical outcome
oooookay Willco.
Cajole nailed it. I had suspected this was coming, but I wildly underestimated how much the writers hate their audience. My major problem with the show's writing staff was the seemingly inability to answer
any questions and drag out this whole ordeal, not that that the writers were incompetent.
That changed last night. It was horrific.
As for ManaByte, I don't think anyone can reasonably argue that the show has answered anything that hasn't been cobbled together by fan communities. Also, saying that spirituality was ingrained in its mythos is laughable. Spirituality was ingrained in Locke's character, who was looking for faith in the face of pseudo-science - not the show.
For much of its run, Lost was about people discovering how some crazy scientists were doing wacky experiments on an island with wacky scientific properties and polar bears and some kind of nano-machine swarm that made clicking sounds and killed people. The "smoke monster" was by its very nature established as some kind of pseudo-scientific entity considering that it was thwarted by - gasp! - science!
The show clearly established a set of ground rules for its universe, one where wacky science was okay. And it has abandoned that in favor of some really shitty, tropical version of Carnivale.
