The Opening Sequence (Season One, Episode One: "Pilot (Part 1)")
After years of mysteries and Easter eggs, questions and answers, numbers and hatches and Ben (oh my!), it's easy to focus on one of the J.J. Abrams/Damon Lindelof/Carlton Cuse sci-fi smash's mindbending moments. But none of them would even have happened if the first few minutes of the very first episode weren't among the most intense and engrossing in TV history. A crashed plane, a beach full of lethal dangers, a motley crew of panicked survivors, and a heroic doctor trying to save them all: the ingredients for a phenomenon, packed into a single sequence about the drive to survive.
