"What is Film Studies?"
I get that a lot.
We know best what we are interested in.
And therefore Film Studies sounds weird to some people. They expect to hear something like "Cinema and Television". The naming depends on the university. And when they hear it, they imagine people working in front of the TV or at the back of TV shows and films.
They do not think that there are film theories, and film studies/Film Studies study those.
It is very likely the same people who assume such things might comment lots on films that they see. How about that?
