I've been thinking about rewatching Lost lately, but I'm not sure I have it in me. Mostly when I think about the show, I remember the frustration and rage I felt about all the dropped plotlines/characters and the unanswered questions. But I also remember how much this show consumed me and how it had so many genuinely good and surprising moments, so that may balance out more for me on rewatch.
I do wish that Lindelof/Cuse would do a series of interviews or blog posts or something to discuss what the original plans were for characters and how that changed. For example, so much is made of Walt being special...then the actor gets homesick and wants off the show so that all gets dropped. And I absolutely agree that it would have been cruel to hold a miserable child to a contract just for the plot of a show, but that doesn't make me less curious about what their original intent was for him (and by extension, Michael). Likewise with Ana Lucia and Libby who were both suddenly killed off after being arrested for DUIs. I don't think they were originally supposed to leave the show so early, so what was intended for them long term? I believe a similar situation also happened with Eko (he wanted off the show, got a DUI, and was killed off). Abd I also wonder how much network interference may have happened (for better or worse).
It would be interesting to see this show rebooted someday, with new showrunners who would have the opportunity to learn from the mistakes made here. I'm fascinated by The Others and the Dharma stuff and what the hell was going on with them, and it's never satisfactorily explained. It would be interesting to see answers for them or how characters would have evolved differently with showrunners who had a grander plan in place (or a network who wasn't trying to push love triangles). But that will likely never happen, and if it does, they'll probably make a whole new set of mistakes for fans to complain about.
