Gerhard Jörder writing about German Theatre maker Thomas Ostermeier:
Ostermeier’s understanding of realism is ultimately aimed at enlightenment. He is in favour of a new substance to theatre, against the arbitrariness of destruction and the aesthetics of “anything goes”. “Especially since people’s social experiences are so disrupted and, in many cases, broken, the need to at least fake something like unity, context and design is growing”: this, he says, is the reason for the realistic approach in his work. But the moral is not in the direct statement; much rather it is in the form.
