My wife and I have watched scores of international detective series. This one is different in that there is almost no mixing in of the detectives' personal lives. It's all about solving crimes through modern police techniques and frequent interviews of suspects. For us, there were two negatives: many of the crimes were extreme ("sick") and there seemed to be excessive use of 4-letter words by everyone. Most of the episodes were self-contained although there were some two-parters and Season 5 followed certain crimes through the entire season. We thought it deserved better than a 7.0 rating.
