As someone who's been a major fan of many TV shows for years and years, and someone who only got into Lost a few months ago: Lost is the greatest thing to ever have been televised. Seriously. Nothing has ever been so immersive, atmospheric and ambitious as this show. It had me gripped from start to finish, and I was genuinely satisfied by the ending (it's incredibly misunderstood). There has never been a TV series as big as Lost, and there may never be again.
