In September, two of my friends began an effort to watch the entire three seasons of Lost on DVD. They've completed the mission just in time for the fourth season, which begins airing next month.
For those of you, like me, who don't have the patience that those two friends exhibited, iTunes is offering a free eight-minute recap of the entire series to date.
