Me too but when I considered that most series I like that have made it past 5 years usually start sucking hard at that point made me give a bit of thanks for the creators to realize they should go out on top and not milk a dead cow for the sake of making money!
I agree, the writers know what they are doing.
I think the sadness part is that once this is over, I will miss the mystery and wonderment—the “not knowing all the answers”. i have done a few rewatches ans it is still fun trying to fugure things out about how this will all come to fruition.
