Sorry, just noticed this after re-reading.

"Most people" is the key. I would say "Most people" also probably wouldn't invest in fine dining either. They'd rather just get something easy and familiar to eat than risk trying something new. It doesn't mean that they can't or won't try something new in the future but more often than not, they'll go with what they know.

There are people of all walks and professions that can and do appreciate film. And sometimes, a film can catch someone's eye and make them want to try it out. But I'd say, much more often than not, people go to the movies to be entertained. They aren't there to appreciate the finer things in film.

And as has been said, being smart in one field doesn't mean that you will appreciate something else. A lawyer could want to go enjoy a fine wine after work but some might just want to grab a beer.
