Kev,
These are the same people who list Raiders of the Lost Ark at #60 in the 100 greatest films of all time.
But people at IMDB, the FANS, the people who make the movies so, list it at #16! You get the smarty-pants hollywood know-it-alls and they take the artsy way out.
I wouldn't worry too much, they're just like the academy, I mean, who won best costume in 1981? Chariots of Fire, my God, how can white shorts and shirts beat out Indy's gear huh? Goes to show where these 'expert's' priorities are, and where their heads are.
