After directing a number of British crime comedies, Guy Ritchie applied his rapid-fire wisecracks, gleeful violence, and flashy cutting and camera moves to the Sherlock Holmes franchise; that same method works well for this big-budget Arthurian legend, perhaps because the king (Charlie Hunnam) and his knights have been recast as streetwise brawlers targeting an evil usurper of the throne (Jude Law). Their antics are enjoyable for about three quarters of the movie, after which the charaters and the imposing production design are overwhelmed by computer graphics imagery. With Djimon Hounsou, Eric Bana, Aidan Gillen, and Àstrid Bèrges-Frisbey as a pouty sorceress who kicks ass just by furrowing her brow.
