The merits of the last night’s final season premiere are no doubt stirring impassioned debate today online and in offices across the country. Indeed, co-executive producer Damon Lindelof told us he expects a mixed opinion about how the show ends. "It's impossible to predict what the reaction to the final episode of 'Lost' is going to be," Lindelof said. "But you know, we can almost guarantee that it will be polarizing, because if it's not polarizing, then it won't be "Lost.'" At the same time, our behind-the-scenes look that followed of the making of “Lost” from inside the top secret set in Hawaii continues to generate buzz in the Twittersphere and on fan sites.
