More and more I'm coming on board with the "magic island" theory. At first it was fun to try and figure out what was going on and the logical explanations for everything. But the further they dig themselves with supernatural occurances (people seeing wet Walt talking backwards, magic smoke, unlucky numbers, Jack's dead dad wandering around, Locke's clairvoyance, polar bears, etc) the more difficult it will be to explain reasonably. Just look out if they introduce a new character that is a cute, precotious, smart alecky kid. That spells the end for sure. Oh crap! Next season the baby will probably be like 8 years old or something with no explanation whatsoever.
