To promote the final series of "Lost," several episodes were made of an "In Search Of..." style late seventies/early eighties unsolved mystery/paranormal mystery series.
Holy crap! Holy crap! This is GREAT! As a fan of the original "In Search Of..." I must say, they totally nailed it. From the buzzing, shrieky music, to the droning narration based around eerie implied threats, to the aged 1970s film look, to the use of ancient frescoes and shots of random crowds.
I finally realized why I love "Lost" so much, incidentally: it reminds me of "In Search Of..." in that what is interesting about it is the weird, subtle awe and fear, as well as the sense of ambiguity about the mysterious. In many ways, "Lost" is like a real-life "In Search Of..."
This one, incidentally, is my favorite because it explains something that I've wondered about for some time: why is it that the Dharma Initiative used, of all things, submarines?
