We have to go back! We have to go back! The most famous words uttered in Lost history, possibly, and after all those months we finally got to see how things turn out. Well, it was a good way to start the season, but we have to hope that things improve from year 3 of Lost. They just did too many things (people in cages, seriously?) and deviated it too far from the plot. Season 4 needs to show us why these people are here and explain how they will get home, and why they have to go back.
Good start, let's hope the season is great.
