I have seen Lost Season one and part of Season two from DVDs at my local library. I do not watch series on regular TV. My schedule is too chaotic. I wait until they come out on DVD. If I see them and like them, then I buy them.
Lost does seem to have a lot of flashback scenes that at times in my opinion make it laborous to watch. I have caught myself fast forwarding on some parts that seemed like fillers to get to the storyline. It does seem to have some twists to it and is an interesting concept.
