Stupid question really, but with the proliferation of Japanese movies to the US and Europe, many more people have had some kind of exposure. So what's your poison?
Me personally, I'm enjoying the insanity being produced by Yoshihiro Nishimura, Yudai Yamaguchi, Noboru Iguchi, Tak Sakaguchi and their peers. I'm talking about movies like:
Mutant Girls Squad (2010)
Vampire Girl vs.Frankenstein Girl
The Machine Girl
Tokyo Gore Police
If you have read my work (esp "de Sade Assassins" or "Media Whores"), you will understand why. The beauty of the over-the-top violence and cheesy graphics is sheer brilliance to me. I realize of course, I am in a minority. But that's just as well.
