Continuity
Sometimes the word is used to refer to any work of art, like just one film.  For example, a woman has a full glass of wine in one shot.  In the next shot, the wine is gone.  In a third shot, she has a full glass of wine again.  That scene would have very poor continuity: it does not make sense, and it reminds the audience that they are watching a movie.  Poor continuity is continuity that does not make sense and usually has mistakes.
