I unreservedly loved Professor Sanders approach to the plays we read in Twentieth Century Central European Drama. He is hugely knowledgeable and able to elucidate the larger picture in terms of small details. The content of the syllabus is beyond fascinating and touches upon a number of topics relevant to the region and era (class dynamics, gender, politics, nationalism, existentialism etc.).
That being said Professor Sanders usually spends the entirety of the seminar lecturing. It would be beneficial to allow for student participation beyond reading passages. Granted this is not always a terrible thing for days where you are just mad tired. Probably should read all the plays though as he will randomly ask people what they thought of specific details.
