It makes no sense for me to do an actual recap, since I'm going to get it all wrong anyway. Basically there are a bunch of people who crash land on a mysterious island that looks a lot like Hawaii. They've been there about 6 years. Some of them get married, some of them have kids. There's a yellow dog and a Volkswagen bus. There's a button that has to be pressed or the world will blow up, and a monster made out of smoke. A mysterious hatch, mind control and and the Dharma initiative are all very important. Don't blink about halfway through the second season. Sawyer looks awesome in a torn wet t-shirt. When the music plays you want to cry; doesn't matter if it's the first season or the grand finale. Everybody who you thought was dead isn't dead. But everybody dies. All characters are both on and off the island at the same time. Some are good, some are evil. The good forgive the bad. The island was a way station, a post crash purgatory.... I figured as much when I saw the beautiful interfaith stained glass window in the chapel right before the end.
For an incredibly complex series, Lost's final episode framed the most basic truth of human experience. Love one another. Help one another. We're on this flight together until it ends. A lofty message for any television show, but one that Lost pulled off with unprecedented originality. It will be missed.
