It's a good show for the most part. I love Berlin, so love the fact it's shot in Berlin. The cast does a good job, especially the young female detective, the plot moves along well. Some of the subtle things are v insightful - e.g. The way the boss speaks about immigrants, the way the young detective interacts with the bloke in LKA - very natural & well depicted. However - *SPOILER alert** - this is a BIG however - I gave a 7 because the motive for the 4 murders is a complete & total let-down!! Ruined a perfectly good show. Pour quoi?! Surely to kill 4 people needs a better motive, come on!!!!!
