The sumptuous production values and stirring performances that make the equally brutal Game Of Thrones so irresistible are nowhere in evidence in Battle For Blood, which has all of Thrones’ savagery, but none of its mystery.

Co-writer/director Jonathan English ups the viscera and nudity at the expense of a compelling narrative, which was hardly the original’s strong suit (if indeed it had one) anyway.

The title's promise of violence is dutifully met in gory, sonically squishy close-quarter melees shot in Confuse-o-vision, as if the camera had been strapped to a whirring blender before the footage was edited with the puree button.

Writer-director Jonathan English’s dank-looking film delivers enough amputations, decapitations and other instances of rusty-bladed gore to distract undiscerning genre fans stuck between seasons of “Game of Thrones,” but serves no other obvious purpose.
