Baby don't hurt me, don't hurt me .. no more. Oh wait the song was What is Love, not life ... well same difference, yes? Actually no and I again used a pop song (you may be familiar with or not) to make a joke but also a point. Because while we may take many things for granted we only learn to appreciate them when they are being taken away from us.
Even the knowledge of our mortality does not seem to bother us. And what would that make us, if we couldn't stop thinking about our demise or when it will occur? Can you "enjoy" life that way? And yet it is there, the invisible "threat", death looming around every corner. And the movie is about a young woman being faced by that ... you see her not having a care in the world. Living, laughing, making plans ... and yet, there are things you cannot plan for.
A really well made drama, about one tragic (?) life event - something that can happen to anyone, at any age! There is nothing that can protect us overall. We can try to live healthy of course and minimize certain risks ... that doesn't mean one is protected from everything though. Great acting involved (which is nothing I say lightly when it comes to German movies) and really well told story. No matter your gender, you can relate to the female protagonist, her friends and family ...
