What is your favourite story line in 'Lost' so far?

Question

Season 5, hasn't been shown in uk yet.. So only from 1-4 seaons.

Answer 1

Is it one big flashback?  Or does it seem that way because certain people on the island change time zones more than their underwear?  Of course if they are stranded on an island they probably only have a few pairs...I digress...

What I like best is the mystery...can't wait to see how they explain the time travel, the polar bear, "moving" the island, etc.

Answer 2

How Jack and Desmond both met again on the island.

Answer 3

I like how the whole time you think that what is going on on the island is in present tense, but then you find out its all one big flashback.
