I have watched all episodes in this Swedish series and have to say that as the series progressed, the quality of writing decreased. The newest offering, produced in 2018 is a much lighter version than the earlier ones. The central character comes across as very tired, and just going through the motions. There isn't the passion and enthusiasm as before. Perhaps this is intentional i.e to show the effects of aging and "burn-out". The newest season has more subplots than the earlier ones, some of which seem to have little bearing on the main story. Although interesting, they can also be a bit distracting from the main focus. Beck's silly and annoying neighbor is still there but adds little to the series other than to insert some Swedish type humor that does not translate well to other audiences. The new episodes deal with current issued of immigration etc in modern day Sweden. Again, in keeping with a need to have a happy ending that is neat, and is a common thread in many of the newer, lighter Scandinavian noir series, Beck is also going in that direction., sometimes to the detriment of logic.

Despite all I've said, the series still is worth a watch but the writing needs to pick up the pace and go back to its roots. .
