I watched every season of Poldark 5 times. I had to make myself stop from watching. I loved Downton and have watched each season 4 times. I loved Shetland but that is not free anymore on Prime so I could not obsess over it. I also loved After Life.
Did you have a PBS Passport? I think it is only $60 a year and you can watch everything. I suppose you watched “World on Fire.”
