I came on very late to the LOST bandwagon. Just started watching last season. The crazy time-jumps made me realize how much of a sci-fi show that it can be at heart, without having to resort to laser guns and constant explosions (not that there's not a place for those, also). Anyhow, I like the fact that it walks the line between a good, clean action drama, and insane sci-fi/fantasy elements. Hopefully, there will be more time travel before all is said and done!
