Lost - The Complete Fourth Season (2007)

While the first three seasons of LOST uncovered each survivor's origins through mind-melting flashbacks, season four has a whole new twist in store: flash-forwards. These glimpses of the future reveal crucial information about who eventually makes it off the island, all the while adding more mystery to a show steeped in compelling puzzles. As for their present-day adventures, the survivors of Oceanic Flight 815 spend the season discovering the truth about The Others and the Dharma Project, and learn that a group sent to "rescue" them may have more sinister motivations. This collection includes all 14 episodes from the 2007-2008 season, as well as a remarkable array of bonus materials such as a behind-the-scenes look at the show's backlot, and a live performance of the LOST score by the Honolulu Symphony Pops.
