I love King Arthur legends so i couldn't miss this. My main complaint here is Jamie Campbell Bower as Arthur.
He looks like a child of Johnathan Rhys Meyers and Kristen Stewart, and not in a good way. And his acting is pretty bad.
I love Bradley James in that role. I know you can't take BBC's Merlin seriously (i watch it as a guilty pleasure) but i always liked Arthur in it. He looks believable as a spoiled brat and as a great future king, and it's a shame that Merlin's screenwriters are not able to pull off a decent show with such cast and sets.
Camelot is better story-wise, but i wish i could just change Arthurs!

James Purefoy and Eva Green are fascinating though.
