Serial Rapist (1978, Kôji Wakamatsu)

Without a doubt, "Serial Rapist" is one of the most violent, to-the-point 'violent-pink' works ever made. It's exactly what the title suggests and, fuck, this movie is a bleak and rapey good time!

A chubby kid in overalls, riding a shitty bicycle, pedals around looking for women to rape and murder. Many of whom, he finds making out with boyfriends or just wandering alone. He seems to enjoy shooting them in the vag immediately after railing them... At one point, he even rapes and then kidnaps a female cop and keeps her in the little shack where he lives...

The film pretty much follows that general idea, throughout. It's basic, but it's done effectively. The rape and murder scenes are ugly and brutal and the nameless rapist character is efficaciously disconsolate and helplessly psychotic. The use of airplane noises and saxophone music during the 'harder' scenes add an interesting element to the uncompromisingly nihilistic tone of the film. Highly, highly recommended!
