ok so mirrormattermoon seems like it may actually be what the writers have in mind. or, if not, it is not likely to be surpassed in elegance by their mythology. mirror matter seems almost certainly to be involved. the moon within earth, specifically, may not be quite what the writers have imagined (wld be remarkable if it is, the exact match). there were repeated pictures of the moon in the film in room 23 in Not in Portland, just watched.

-if this is the actual mythology (is that the right word? the setting - where & what the island it and how it has unusual properties, incl difficult to find), it does not 'ruin' the show - does not answer aspect of what will happen: still do not know what the writers have planned for the characters, and especially how it will end. how will the adam & eve skeletons show, as lindelof said would, that the writers knew from the beginning what the end would be?

-and why were the Others so hostile to the crash survivors, killing & kidnapping? why not just be nice, gather them in? well I guess it's clear that they are not an unknowing community of people collected by the island. they - or at least Ben - have some specific knowledge and some specific motivation. what? what are they doing?

these seem to me at the moment the outstanding questions (that I would like to look back at, after the show ends, and be able to answer) -motives of the others -adam & eve skeletons tying in to the end
-oh and a specific that I'd like to know: why Richard Malkin told Claire that her baby must not be raised by an other *and* put her on the plane that would crash on the island where the others are.
-meanwhile also how Naomi comes to have photo of Desmond & Penny
