Well that is that then.
As far as things an enjoyable final episode, that did what it needed to.
I was sure that if they ended it there and then, with Arthur's reign so short that I would have been disappointed, but somehow it all seemed to work nicely.
I think they made the right call to stop it where they did, and actually felt it made sense. Arthur may not have had a long reign, bringing peace to a violent land was all he managed. Maybe that was enough.
Gwen could well rule for a long time in his name, and enjoy a peaceful time. But would it be remembered as hers, or the king that made it possible?
Somewhere down the line someone telling the story would have said, surely it works better if Camlann were at the end, not half way through...
So I'm happy with it, and can think about it over Christmas.
