I saw the movie yesterday although I had read about the reviews saying it was a 'shite movie'. I didn't actually think it was all that bad btw.
Apart from the miscast of the guy who played King Arthur (who didn't really believe in what he was doing half the time, or it seemed like to me), the rest of the actors were quite good. Especially Lancelot and the other Salmations. There were great character developments and some brilliant fighting scenes (e.g. the ice lake). And it being about historical events (which I have a strong fondness for), I ended up enjoying the movie all up. I'd give it around 7/10.
