I believe you mean "abstruse".Summer school, to my mind, is about more detailed and difficult talks than a run of the mill public meeting. A great many workers are interested in Shakespeare and history, and the actual subject of the meeting, ideology and its workings, is sufficently difficult that an approach through something as tangible as a scene in a film is a useful way of introducing it.
