Running through Lost for the second time, you have a greater appreciation for what the show is about, especially with regards to the various happenings in the show, that while appearing some five seasons in, were foreshadowed from the very beginning.
Also being a big fan of who is clearly the protagonist of the show, John Locke, I've decided to throw together some of his best bits for prosperity's sake, starting with the excellent "chin-wipe-grin-chuckle" moment, for want of a better description. :)
