Season 2? (spoilers)
Netflix hasn't announced a season 2 yet. And they have been more liberal with canceling after the first season with some shows they expected to do better.
Since it is #1 right now I think the chances are good.
It will be interesting to see how Nimue (Lady of the Lake) will continue with Arthur and who I assume to be Gwynevere (Red Spear). I think this was an interesting take on the Arthurian Legend since it has been done to death. And revealing certain characters slowly and in different ways. I should have realized the Weeping Monk was Lancelot but it took the 9th episode for me to figure it out. Squirrel as Percival was a nice twist.
