Creditable Movie

At present the two Reviews for this film are tending towards the negative, but I can see a case for it to be rated substantially higher than this. (Philipp Eichholtz the Director has won a Nomination for it, so some people in Germany must rate it better than that.)
The film is true to being true-to-life. There are people who do, in common judgement, seem to live on the edge - too much 'vitality', too much 'energy' and their life can seem to fall short of the normal progression. Sarah is presented as falling into this typology - and her story is presented very well as she seems to veer from one relationship to another. But, as a quick plaudit, credit to the film for portraying such a character in all her myriad character facets.
But the film advances beyond this surface linear plane - it shows how hard life can be when one is lacking the stability of a steady job, a steady income, and steady family support. In a way the film presents a plea for looking beyond such issues, and appreciating the goodness of character in people whom we might lightly dismiss. Certainly Sarah has her problems, and her impulsiveness is a major one, but the film presents her case with great strength and can be given praise for its complex passage of plot as our spirits go up and down with her own saga.
I see the film is criticised for having a 'do nothing' ending but it can be argued that we don't need every film to neatly and tidily tie up all the loose ends - arguably each viewer can be presented with the story of a character on a journey and the ending can just be another chapter in this story, and the film can come to a restful stop leaving it up to us to imagine what might or could happen in the future. (Let us appreciate what we do get, rather than criticise what we don't get.)
