LOS ANGELES Some 13.5 million Americans watched the last episode of TV mystery adventure series "Lost", ABC said on Monday, but many critics and fans concluded the long-anticipated finale raised more questions than it answered.
The ABC network said the emotional 2 1/2-hour finale was the most-watched show on U.S. television Sunday night. Some 9.8 million watched a special retrospective, "Lost: The Final Journey," earlier that night.
TV critics and fans of the award-winning show had mixed feelings about the conclusion of the tale of plane crash survivors stranded on a mysterious island.
Newspaper USA Today listed 10 top questions that it felt had not been cleared up, including why the island needs protecting and why babies can't be born there.
In a review headlined "No Longer 'Lost,' but fans are still searching," Mike Hale of the New York Times said the episode was "largely a pleasant, nostalgic wallow for the show's fans."
Mike Ryan of Vanity Fair said the big revelation -- that the flash-sideways dimension was actually the afterlife -- overshadowed some of the answers that fans were expecting.
"Every question that's still lingering -- and there are quite a few -- is inconsequential. None of the actual events matter --it was only the journey that mattered," Ryan wrote.
"Lost", which began in 2004, was one of the costliest and most ambitious shows on American television and gained a huge following around the world. It has won 58 awards, including Golden Globes and Emmys.
