The Tagesspiegel has a good old rant about the caution and backwardness of Berlin theatre:
All das existiert bis heute, es ist die Avantgarde von gestern und vorgestern. Wie modrige Pilze. Die Formen und Mischformen erzeugen kaum mehr Reibung, sie werden mehr oder weniger aufregend recycelt.
You want to pat the author on the back, give him a pep-talk. I don’t know nearly enough about the Berlin theatre scene to say whether it’s accurate; certainly there are few people with a positive word to say about Berlin theatre at the moment. My feeling, though, is that the big and famous theatres are
always
boring, in every city. The interesting stuff is going to come through newer, smaller venues, of which the article avoids much mention. HAU, for instance, seems to be the epicentre of interesting theatre in Berlin, with a constantly-changing programme that puts the bigger places to shame.
On the other hand, much of HAU’s content comes from touring companies; that might not make them the best advert for Berlin thetre.
