There's no denying that Games Workshop's Warhammer 40,000 role-playing game has plenty of scope for spin-off movies. This makes it all the more surprising and disappointing that this CG animation is the first attempt at bringing the game's rich universe to the screen. Sure, Ultramarines may get the small details right, but the characters are mere cyphers, the pacing is dreadful and the plot is as predictable as they come. The Blu-ray's AVC 1.78:1 visuals look oddly washed-out and lack texture, while the Dolby TrueHD 5.1 mix goes for volume rather than quality. A missed opportunity.
