I have watched all the seasons to date and have noted a significant decline in the writing. I gave it 5 stars because of the early seasons but the latest series, 2019, is just a waste of time. It's as if all involved in the production have got tired and want to move on to doing something else. The repetitive depiction and stereotyping of "Siciliana", is overdone and becomes annoying after a while. It may be that it remains popular in Italy but certainly wont sell globally. I think after a while the production team should know when to wrap it up and allow Montalbano to exit gracefully before it sinks to a new low.....a terrible way to end what started as a good series!
