If people are too stupid to watch a movie with subtitles, they're too stupid to understand the psychological and sociological subtleties that permeate Larsson's works, not to mention his commentary on Swedish society.
I never said stupidity had anything to do with it. It probably doesn't, either.
Well that's what it boils down to essentially. They're stupid because they're lazy because they're stupid. And by stupid I guess I really mean ignorant. Willfully ignorant.
