I would love to see DS04 - it's the only version I've never seen. I wish they'd just release it to youtube or wherever, even in its unfinished state, and let the fans enjoy. It's not like it can ever make any money. Consider it free publicity to expand interest in the franchise. The unfinished pilot of Lost In Space is available on youtube for fans to enjoy; why not this one? Why keep it under lock-and-key? From all that I know, it's already been shown (several times, I think) at previous fests; the vast majority who've seen it have seen it.
