The Crown season 4 - two thumbs up. Definitely the best season yet. For the first time, each episode had some kind of historical event happening. In previous seasons there seemed to be 'filler' episodes where nothing much happened in a historical sense. When the show was just left with whatever emotional drama between the characters to deal with. I think that the added focus in each episode strengthened the season overall. Looking forward to seeing how the creators wrap things up in the final 2 seasons.
