Although this thread is old, i wanted to drop in to say my opinion. While lost is generally a mess maker in your head, at the end of season 4 it clears a lot of things up, which for me, solves the main/adventure part of it. The psychic/whatever part of the series has yet to be explained but i would recommend everybody watched is now, as you can literally watch all the episodes till season 4 and have a good understanding of what happened.
Imagine the other poor folks that watched it as it unfolded. They must have been mad & madder by each episode
