See it if historical theatre, esp. Toller's German self-critical realism between the world wars in the formative years of the Third Reich, intrigues
Don't see it if you cannot focus for continuous 105 minutes in uncomfortable seats on clunky, Germanic construction, clumsily spoken dialog with no surprise
See it if You have a friend in the cast.
Don't see it if You dislike clunky translations where the director does nothing to draw out the comedy or the interesting in the text.
