From the first harrowing, heart-stopping moments of its record-breaking $12 million pilot to the closing scenes of the season finale, Lost is a roller-coaster ride the likes of which hasn't been seen since Dr. Richard Kimball took to the road in search of the one-armed man. Emboldened by the success of Fox’s thriller 24, which similarly employed an ambitious narrative arc, ABC took a chance on Lost’s daring concept: Survivors of a plane crash wash up on a mysterious tropical island, where the hardships include starvation and clashing personalities, as well as some sort of evil creature, a weird metal hatch, and...a polar bear. The talented cast -- along with supernatural twists and strange occurrences cooked up by the creative team -- made Lost an instant TV hit and make it an even greater delight on DVD. Matthew Fox heads up the 13 regular characters as Jack, a doctor who becomes the leader of the ragtag group. Filling out the cast are: Kate (Evangeline Lilly), a beautiful girl with a dark secret; bad boy Sawyer (the mesmerizing Josh Holloway); Sun (Yunjin Kim) and Jin (Daniel Dae Kim), a Korean couple whose marriage is on the rocks; father-and-son team Michael (Harold Perrineau Jr.) and Walt (Malcolm David Kelley); devoted stepsiblings Boone (Ian Somerhalder) and Shannon (Maggie Grace); former rock star and heroin addict Charlie (Dominic Monaghan); good-hearted Hurley (Jorge Garcia), who provides comic relief; former Iraqi Republican Guardsman Sayid (Naveen Andrews); Claire (Emilie de Ravin), whose pregnancy survived the crash; and philosophical survivalist John Locke (the fantastic Terry O'Quinn). Each episode focuses on one or more of the characters' lives, and through a combination of flashbacks and current events on the island, the audience is introduced to a felon, a murderer, a lottery winner, a torturer, and a Mob enforcer, among others. If we had to choose the best episodes of the season, they would have to be: the Emmy-nominated "Walkabout," in which we learn the truth about Locke; "Hearts and Minds," an episode that delves into the strange backstory of Boone and Shannon; "Outlaws," which examines Sawyer's disturbing childhood; and the season-closing "Do No Harm," in which Claire's baby is born just as a major cast member exits.
