I don't know why this is so shocking. Not everyone thinks SW movies are the greatest films of all time. In fact, some of the people closest to me think they kinda suck. But the fact that ESB made it to the finals is a pretty impressive sign--it won out against Alien, T2, Robocop, The Matrix and 2001. Io9 is a hard-sci-fi site and I'm surprised ESB got so far, because its a fantasy film and not hard science at all. I guess Serenity isn't either, but it definitely is the sort of thing that readers of that site would put in the finals. And, like many others have said, its a terrific film to one of the best sci-fi works of all time, let alone on television.

Personally, I think 2001 should have won. If this was 1990 it would be an outrage that anyone could think otherwise. But the relevance and popularity of older films wane and preferences change as newer films give you more choice and introduce new classics.
