Part of me wants to watch the entire series start to finish so I can enjoy the answers that were (eventually) provided, but another part of me would find that so incredibly frustrating because there were so many things that were never addressed. I'm cutting-and-pasting two of my earlier questions:
When we first learned about the Others, we saw glimpses of them walking through the jungle: single file, barefoot, dirty, and (if I remember correctly) one of them dragging a stuffed animal. The Others that have played an active role in the last couple of seasons have not resembled that at all. What's the explanation?
When Kate, Sawyer, and Jack were in the cages in Others Village, the stewardess (Cyndy, I believe) and children from Oceanic 815 showed up. Cyndy told the prisoners, "We're here to watch." What was that all about?
I guess I could live without an explanation for the second one, but I really, really, REALLY want an explanation for the first one. Despite their claims otherwise, I don't think that the writers had a clue where they were going at several stages in this series. That's not to say that I didn't enjoy the ride, but I do feel a bit frustrated.
I won't even mention Walt...
