Check out this map of the LOST island, made by a professional cartographer, at this link.
Go ahead and skip the comments, however. Something about comments brings out the people who get pleasure out of typing "LOST was bad"; at the same time, few comments are made about why so many people watched it for so long. Remember how a few posts back I mentioned that the comments were an example of the Internet working like it should? Well, this is the opposite.
Was Harry Potter this way? Because I feel like Harry Potter explained things about as well as LOST, and I don't remember this general vitriol toward the series after it ended.
