As many of the other reviews have said, Lost is a slow moving programme. Many of them say that nothing really happens but they seem to be missing the point of the show.
Firstly, the main story line is going to take six to eight seasons to complete.
But the main thing i feel people are missing is, although the events on the island are the most important parts of the show it's not what the show is about. it's about how the decisions in our lives lead us to where we are going. as with all the best tv shows, Lost is a character driven show and is nothing without the complex back stories of who these people really are. over time, i feel lost will become a part of TV history as it's this character depth that makes this show stand out above the rest.
If your one of these people who want everything spelled out for you, Lost is not the show for you. But for anyone who enjoys a show on a more personal level and not only enjoys what happens in the seen but how the characters are involved and affected by the events then Lost is the show made for you.
