The show frequently shows nice views of the city of Leipzig.
I'm afraid that this is the only favorable remark I can make about this show. It is probably the worst murder mystery series I've ever seen. All cases are extremely unrealistic (much more than usual) but appear to be meant realistic. Each storyline has a complete turning point every five to ten minutes (makes 4-5 such surprising developments per episode). This means that the end is not usually predictable but despite that I could never feel any suspense.
The actors are unable to alleviate the abstruse and convoluted plots. Their characters are the generic combination of some young inspectors (presumably deemed attractive, of both genders) and a senior supervisor. None of them creates the impression of an authentic police officer. Again, this may be due to the hopeless stories. But maybe not.
