Unfortunatly, telling you what Lost is about is an act of foolishness. it cannot be properly described, or praised. It's basically the best show of all time. Any LOST fan will tell you that.
but, basically......A group of strangers crash on an uncharted island when Oceanic Flight 815 breaks apart in mid-air. stranger and stranger things bring the survivors closer together as Destiny seems to lead them own a seires of events that changes their lives, their faith, or lack there of. Because this island, isn't an island. It's a place where miracles happen. And you if can't believe that. Just wait till you see what they're about to do. (if you end up watching the show, that line will make sense...eventually.)
apart from that it's a great show to watch blazed. the music, and blackouts at the end of the episodes are beyond awesome everytime. even the commercial breaks are well placed. but all the episodes so far are on abc.com as well as dvd, and your bit torrent site of choice.
(can you tell I'm a fan?
