To say the most important thing first, I liked the film a lot.
I liked the story dealing with questions of guilt and of identity. The film appears very structured and "clean", not many different characters are visibly involved - a modern "Kammerspiel" (intimate play).
The reactions of Maria, Anton and her new found family are always authentic, never over the top. Even though (hopefully) the majority of the audience has never been in a similar situations it grips you and you keep asking yourself "What would you do?". Of course the plot is not always fully logical and it left me with some open questions (who is Maria? is she single? does she have friends? a job? what happened to her German mum?) but it made me think about it quite a lot.
Little details suddenly sprang into my mind like the fact Maria calls her (as she doesn't know then) adoptive parents by their first names only.
My positive feeling about the film is probably linked to the fact that I like Jessica Schwarz as well.
In a way it is like "Lost in Translation" with a more substantial key conflict.
Only one little thing was annoying - yes, Maria is supposed to be a swimmer. But that doesn't mean that outside the pool in 99% of the time she still wears tops with racer backs. Her shoulders and whole body look great and toned, yes, but we got the message.
