I take the bad reviews here are due to this film either not are being understood, or that some refuse to take it in - the danger of youth wanting to change society from what it is today, maybe drastically. It's not a coincidence this film is made by Germans. It comes with a warning.
A reference to this film would be The Wave, which is filmed both by Amercans and Germans, based on a true story.
This movie starts off very interesting, and within 15 minutes I'm sold.
We see a young couple driving across the border into Germany hiding a refugee which they smuggle in. Then we wind maybe 20 years forward, where we see the same family being freak hit by a terrorist attack. And this leads to us following the daughter Maxi and father being left broken. The daughter is being approached by journalists and others, among them a very charming an pretty young man, in whom she involves.
The film is well mde, but doesn't overexplain. It's down to you as a viewer to decide what you see. I think many modern viewers watch movies while they look at their mobile phones. This makes them need aoverexplaining to get the point of a movie. They are easily confused by narratives and jumps in time.
This film gives warnings. Warnings which makes me think of the environmental movement more than nazi- or terrorist-movements, but this is fiction which comes with a warning, put into an interesting story. Just watch it with an open mind!
