...other things are odd. Editing for example, a still image of the eye of the victum. A still image in a movie is odd.
Then there are the magnifications of close ups, the editor zoomed into a closeup. The result ist the same as with the still image, the film grain becomes all too visible.
Next, the actresses playing mother and daughter are just 10 years apart. Yeah, Sean Connery and Harrison Ford were also only12 years apart as father and son respectivly in the Last Crusade but Connery without hair lood older. Here mother and daughter look really old and it does not work. One gets confused.
The story is not bad this time, the characters make sense, the motivations and motivs make sense.
But it is odd, something in a Tatort is always off, bad, not right. A little more effort soemtimes and maybe you have a special epsiode. But not like this.
