Why It's Smart: What started as a simple desert-island drama has morphed into a dense, kaleidoscopic serial that really bakes your noodle. For every question the show answers, it raises five intriguing others. Why did Oceanic Flight 815 crash? We're really not sure, but it has something to do with electromagnetism, time travel, redemption, absent fathers, fertility issues, an abandoned nuclear warhead, and some guy named Jacob… so far. It's a wild ride.
How Smart Is It? Among the staggering number of books woven into the show's mythology are Homer's Odyssey, Shakespeare's Julius Caesar, and Stephen Hawking's A Brief History of Time.
