I have been hooked on "Lost" since it first aired four years ago.  This intercontinental flight from Sidney, Australia to Los Angeles, California that broke apart mid air and left roughly 50 survivors to fend for themselves on an island that has, to say the least, been quite a challenge.

Flash backs about each main character tell the viewer what personality flaws have brought them to this juncture in their lives....or death.

One thousand miles off course,either drawn or thrown, these survivors have encountered a mysterious black cloud of evil and a group of "Others".

Then we find that the tail section of the plane had survivors too and they meet up with the front section and the group grows. We've loved and lost some; each bringing more questions.

And what is the Dharma Initiative?  Is is a biodome or another attempt to develop a superior race?

This season brought us flash forwards of the Oceanic Six......who are they?  So far, we know it's Jack, Kate, and Hurley.  How do they get off the island?  What happens to the other survivors and the Others? And will the Oceanic Six go back as Hurley has told Jack they should?

Any ideas?
