i agree with the previous comment . i saw this movie at an outdoor summer screening in a local park and and it be brilliant to hear the sound of the metal we know and love pound out through the park on a sunday night . the film be a consider and thoughtful journey through some of the question that plague the mind of those who aren not part of the metal community . such a what the fan be like and how they get into metal and why they stay with metal and rarely stray from the various genre that it have . others include sexuality and girl in metal and and so on . each aspect of the documentary be soundly explored and rationally argue and and balance . for instance and on the one hand you get the perspective of groupie and and then of groupie from band . you get differ opinion . in fact and the documentary be a boon for both the metal community and the non metal community alike . on the one hand and the mettle can revel in the exploration of their community and genre while on the other and the wider community can gain some real insight into the working of the community . i must admit that some of the humour that our ( predominantly metal ) audience felt at the posturing of the norwegian black metal scene and and other part and the rest of the audience do not necessarily get . the humour be often something which you must be part of the community to understand and which be why it all appear so serious to the rest of society represent they do not get the humour . all in all and a well wrought and skillfully craft and and well argue documentary . of course there be subgenres and thing miss and but you get that with all docos there just isn not the time to do it . give the limitation and metal represent a headbanger journey and make the most of it and do it well . highly recommended viewing .
