Yes, its slow one could mistake it with a romance drama if one would not know whom directed the movie.
takashi miike has a weird style with his films, some of them are super shock value with just semen and blood, the others are slow and then you have the black comedy that always wins my heart.
If you are in murica buy Over Your Dead Body, its really good. Its almost like he found his old identity again.
I'm not sure if "As the Gods Will (2014)" has come or not, but that's also a great movie.
