I felt betrayed by the last season when watching it when it aired. However, seeing it a few years later with some distance to the characters etc, the last season becomes more clear and I would define the show itself a masterpiece.

There are parts, especially in the last seasons, that are a bit rushed and there are some topics that do not receive (much needed) clarification. Would give it a 10 compared to other shows but compared to itself and what it could be, I feel it's a right above a 9. It needed 1 more season and a bit more depth and clarification in the last parts.
