Awesome!!
Season two is my favorite so far; "The Lady Of The Lake" is my very favorite episode. Me, too. I watched it one afternoon when I was bored and went on a marathon I loved it so much.
From what I've heard, a lot of people dislike the way her romance with Arthur sort of came out of nowhere and so they see her as a "Mary Sue" sort of love interest. I think probably they weren't familiar with the legends so they weren't expecting it since she pretty much disliked Arthur at first.
At this point I should probably confess that I'm a Lancelot/Gwen shipper who enjoys Arthur/Gwen, too. Technically both are in the legends so they're 100% canon but I've always liked Lancelot/Gwen better because they have AMAZING chemistry.
