Good God, this Arthur is a douche!
I've seen quite a number of adaptations related to Knights of the Round Table, but this is by far the worst and unrootable Arthur. The whole Guinevere thing was awful, not only the first time, ON HER WEDDING DAY, but in the last episode as well. Her husband just died the day before saving his life, and he had absolutely no problem banging her after. I know she was Morgan, but from his point of view, she was Guinevere... it's simply impossible to root for someone like that.
Plus, there is also something about the actor that simply rubs me the wrong way... can't quite put my finger on what it is.
Great Merlin though.
