Review: Not being a big fan of Japanese Gore-Sexploitation movies, I still found myself curious about these kinds of films. My last experience with these types of movies was a real disappointment but I decided to give a chance to another one, just for the heck of it. I was expecting again a horrible experience but this time it didn't turn out that bad, it was more enjoyable and tolerable than before. This time the movie centered more on the development of the story and the characters, unlike other movies of its genre that just try to show you exploiting useless rape scenes and extreme gore.

The movie starts very slow and takes the time to build up an interesting story about an ambitious young man who only thinks about himself and doesn't care of the consequence his actions. The story of Naked Blood has a lot of meaning in it and unlike other Japanese exploitation movies; Naked Blood uses its story not only to shock people but to make them think about the emotions of the characters. The movie may not have reinvented the genre but has at least accomplished to give us a decent story, something that most of the time was used as a pretext to show disturbing scenes.

Naked Blood, which is directed by Toshiyasu Sato, who take a step away from his regular rape-sex movies; delivers more than just a mindless exploitation movie this time. It would not be fair to see the movie as just another exploitation film but we can't hide the fact the Naked Blood is not the big meaningful movie that it has tried to be. The story is very simple in all but it also tries to surprise you with a couple of interesting twists and a good ending, at least that makes the story surprisingly enjoyable for that kind of film. Technically, the movie is also a lot better than what I expected. Some scenes looked really well and it was apparent that the director paid attention to what the movie will end up looking like. The movie is maybe not ground breaking in the cinematic department but it didn't look like an amateurish movie that most of these films look like generally. And for a movie filmed in less than 7 days, it was not too bad.

The biggest challenge that the movie had to overcome was to make the characters likable. A really big challenge since usually in these types of films most the characters are there just to be killed, raped or both. Eiji, the main character, which is the starting point of every atrocity happening in the story, was in general very well played and looked like one of those stereotypes disturbed Japanese teen kids. His mother was also great but was maybe the hardest character to understand, spending a lot of time in front of those old family videos to remember her lost husband, she was a little strange but never to a point of total annoyance and misunderstanding. The three main female actresses were probably the most important characters of the movie, since everything fell on them without warning. The story takes the time to let us know each one of them, telling us their problems and their joy in life, which will turn against them in their near future. Of the three girls, the movie centers more on Rika, the girl that Eiji will become obsessed with, she is also the strangest girl of the unfortunate trio.

The movie, which has a running time of only 75 min, is not filled of extreme gore from start to finish. The movie has a really slow buildup and really takes his time to let us understand the story and his characters. But when the gory scenes finally appear, they may not last very long but they are very intense and shocking. These short disturbing moments are very well made and some of these effects really look convincing on screen. A few examples of these scenes consist of extreme body piercing a la Night of the Living Dead 3, self mutilation, cannibalism, extreme burst of blood and more. Even if the movie has a lot of sexual allusions, there's only one sex scene in the whole movie. This scene, at least, was there for a reason and had some importance in the story, unlike other exploitation movies that like to throw at us rape scenes just for the fun of it. Amateurs of intolerable violence will enjoy these violent moments a lot, but as I said, there are only a few of these scenes in the entire movie. But maybe that was a good thing because I'm not sure If could have stand a full hour of sadistic violence of that level.
