I've only watched a few episodes and the plot seems extremely interesting. I don't know if they're going to end like Lost or if they're really going to explain us what happened but it doesn't really matter. What matters is that the actors are terrible and it makes the show really difficult to watch. If they take the "Lost" approach, they've already failed because we cannot get attached to the characters.
Unnecessary love stories, some uninteresting drama, bad actors, no memorable scene, but overall good plot.
