Currently downloading Ep 3 from australia. We still haven't screened Ep 1 so im not waiting. Spoilers warning please.
My theory, its not ghosts, its the ability to actually confuse timelines on the island that has allowed Jack to see his father, Kate her horse, Hurley Dave, etc.
I think that 1st ep. really lays out what the ultimate explanation is going to be. Its about time being irrelivent, nothing else matters, so that is how anything spiritual should be percieved.
“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
