To put it simply, if you don't like a tiny bit of gore, then maybe you shouldn't watch this movie. However, if you can put up with a little bit (minor misjudgement) of blood on the screen, then this film is definitely under the bracket of masterpiece. The story, while at first hard to follow, is pure genius, complex enough to create interesting enigma's, but not so complex you lose track of where the film is going, and therefore interest. The other point to make is the use of the violence. Whilst the redness of the blood could be compared to Argento or either of the Kill Bill's, Miike's excessive use is genuinely jaw-dropping. The people I viewed the film with found many of the images disturbing, but when analysed, they add a deeper layer to the film than what first appears on the screen. All except one piece of the violent imagery are done concocted with outstanding visual effects, and make even some Hollywood films look basic. Overall, I feel that as long as you can put up with the gore, then you are in for one hell of a ride!
