I kind of think it's nice, actually. The casting is weird, but I think Eva Green makes one of the best Morgans I've seen depicted on film, at least thus far. The scenes are gorgeous, and I love the costumes. I also kind of like the little attempts at historical accuracy, like the giant bread trenchers in the first shot, how no one is wearing different clothes every other scene, and how life is pretty simple and kind of sucky but it is just the way it is so it isn't exactly emphasized? I also found it a bit weird that they made Morgan Uther's daughter instead of Ygraine's, and that SPOILER Lot dies in the pilot ? but I mean, Sir Tomas Malory wasn't exactly basing his writings on historical fact, so it is really always left up to interpretation, and while some people do a better job than others (cough Marion Zimmer Bradley cough Mary Stewart cough), I can work with it.
Also Guinevere has excellent tits, so.
