Watched at Berlinale premiere.
While the film mentions quite a few interesting topics (class vs. ethnicity, white guilt, religious rules), it never takes a try at debating any of them. Just mentioning the problem seems to be enough here.
The plot itself tries to create tension, but suffers from giant plot holes, until the end when they don't even try to make anyone seem reasonable. Unfortunately, this doesn't go beyond average german tv movie standards.
