This is a German TV 2-part movie, and really is far better in almost every department than even the many higher profile & higher budget fare you get in the crime & heist genre you get in the English speaking world.
We have a curious case of a prolonged bank robbery led by a dangerous and frightening lead, who is able to take advantage of the bureaucratic and hand-tied authorities to string out his crime to try in a vain attempt to escape.
This film is brutal in its honesty about the different elements involved: the criminals, the police and the abducted. It's brilliantly paced and filmed, and you can't help but feel sucked.
A great experience, and really wouldn't be surprised if this is copied or influenced to others abroad in their efforts in years to come.
