Lost Leaves many questions

Sci-fi TV drama "Lost" ended six seasons of plot twists in an emotional finale that saw forgotten characters reemerge, an epic battle among key rivals and still more questions in the mysterious island paradise.

Fans looking for answers to the series' numerous mysteries were treated to the reappearance of characters from seasons past like Boone and Shannon, who served as catalysts to trigger memories of the island for those struggling to remember.

Perhaps it was predictable that the "Lost" creators would reintroduce old characters and leave new questions unanswered. After all, they had already warned they would.

Producers Damon Lindelof and Carlton Cuse said in advance that the final episode's storyline would continue on a season six DVD with upward of 20 minutes of additional material.

Part supernatural adventure, part character-driven drama, "Lost" has evolved from the story of 48 survivors of Oceanic flight 815 who find themselves stranded on a mysterious island into a complicated, mythological tale with an expansive cast.

The series-ending season No. 6 began in the post hydrogen-bomb haze of the 1977 Swan construction site explosion, and it progressed at a break-neck pace shifting through time periods and giving more back story on strange characters like Richard Alpert, Jacob and The Man in Black.

Sunday's finale, the 114th episode fittingly entitled "The End," saw the island's new protector Jack and the nefarious Locke/Man in Black, fight it out for control of Desmond, who served as both a tool to be used and a weapon because of his tolerance to electromagnetic energy, and the island's fate.

Jack later sacrificed himself to bring the mythical "heart of the island" back to life, watching a plane glide through a jungle clearing before closing his eyes for the last time.

Kate, Sayid, Charlie and the other Oceanic survivors in the show's alternate "sideways" reality began experiencing flashbacks of their time on the island, leading them to remember they are somehow intrinsically linked to one another.
