That is, there's a certain bit of technical jargon that one will run into if (s)he reads critical analyses of films. Me, as just some dude watching at home, I know what an eyeline shot is, for example, can point out these mechanics when presented or even violated on screen (Ozu), but to me or those who don't know the terminology, how much does knowing this actually enhance the quality of the movie-watching?

As an audience member or student, how important is it to have a grasp on the technical language of a medium?
