If you are looking for subtlety you are in the wrong place; this film is full of bloody ninja action which sees limbs severed, heads cut in two and blood all over the place. This starts in the opening scene so if you can get past that you should be okay with what follows. The action may be highly
choreographed and occasionally CGI enhanced but it is still thrilling and frequently wince inducing. The story is fairly simple but that doesn't matter; it is there to justify the action and it does that just fine. The cast are solid; K-Pop star Rain impresses as Raizo and Sho Kosugi is suitably mena Lord Ozunu, his once mentor now the main villain.
