There was something really special about the first couple of seasons that were set in Scotland and post WW2.

The British Empire, the Battle of Culloden, Scottish Highlander culture, and time jumps to the 1940s and 1950s, showing the ruins and old castles in real time vs their peak when they were full of life etc. were all extremely interesting. It was also framed in a way that made it feel believable. Unfortunately, starting with the France timeline it just got repetitive and any sense of believability just went out the window. It's like they go out of their way for these two to meet every major historical figure from the 1750s in Europe to the 1770s in America. The Colonial America timeline is pretty much unbearable at this point. Besides the repetitive storylines, it's just too clean and tension is just created for the sake of creating tension and doesn't seem to have any part of the story and isn't how people would act in those situations. I've kept watching it because the two leads are amazing and I keep hoping it will capture that same magic from the first season but that doesn't seem likely.
