Documentary tracing the history of the slasher movie from 1960 with " Peeping Tom" and "Psycho" through to the present day( or near enough).Based on the book of the same name,this documentary it must be said offers nothing new and much of it is recycled to the point of tedium for the knowledgeable horror film fan.Film is quite extensive and covers pretty much all chapters and interviews all the directors and producers from the first wave of slasher films from 1978 to 1984.There are plenty of scenes from the classics of the genre and is clearly made with respect for the genre.The film is for horror fans of which i am one to wallow in nostalgia and purely for this, film is a success.Good.
