Extreme cinema (or "hardcore horror"[1]) is a subgenre used for films distinguished by its use of excessive sex and violence, and depiction of extreme acts such as mutilation and torture. The rising popularity of Asian films in the 21st century has contributed to the growth of extreme cinema, although extreme cinema is still considered to be a horror film-based genre.[2] Being a relatively recent genre, extreme cinema is controversial and widely unaccepted by the mainstream media.[3] Extreme cinema films target a specific and small audience group.[4]
