Also, EW.com has a great article discussing Lost’s 17 Enduring Mysteries. It tackles everything from the big mysteries of “what is the monster” and “what are the numbers” to secondary/minor mysteries like what’s the deal with the Dharma polar bears. It’s an interesting, yet cursory look at all of the overarching questions still left unanswered as we enter the final homestretch and await the Lost’s final two seasons.
