Strawman Has a Point: Roger Ebert (a Pulitzer Prize winner for writing) found himself taking the sides of the students who complained about the uselessness of their grammar lessons. The film doesn't make the students Straw Characters, though, far from it, but we're expected to take the teacher's side about the lessons.
Ebert: As the students puzzle their way through, I don't know, the passive pluperfect subjunctive or whatever, I must say I sided with them. Despite the best efforts of dedicated and gifted nuns, I never learned to diagram a sentence, something they believed was of paramount importance. Yet I have made my living by writing and speaking. You learn a language by listening and speaking. You learn how to write by reading. It's not an abstraction. Do you think the people who first used the imperfect tense felt the need to name it?
