BERLIN IS IN GERMANY is what an outsider hopes to get from a new European film - plausible (well mainly) picture of it's society, vivid characters here represented by unfamiliar faces ( Platerenau's final appearance is a nice surprise), a different look suggesting extensive available light photography - throw in a bit of sex and violence.
This one is considerably better than the Gabin film MELODIE EN SOUS SOL which uses the same situation - released prisoner returns to a home town he no longer recognises.
Its placing in Berlin is effective even if they labor the East-West theme. It leaves you interested in seeing the other work of its performers and writer director.
