a thought provoking and interesting documentary about one of the most popular and controversial genre of music around today . discuss topic like religion and sexuality in the world of metal and this feature some fascinating interview with pretty much everyone from geddy lee to george fisher . for those unfamiliar with the genre and or those who consider it pointless noise and this should hopefully open a few eye . the director and sam dunn and a self confess headbanger himself and have clearly research his topic greatly and and whilst the geneology chart may need a few tweak ( last time i check and cradle of filth be english and not norwegian ) and the footage and interview provide more than compensate . it address the music critic head on and whilst also provide u with some very funny story from the life of it subject . the interview with dee snider about the pmrc be particularly hilarious . and best of all and it have a killer soundtrack .
