here be spoiler to some degree . in an informative piece such a this movie i do not think it matter too much and but you have be warn . i know most of you out there do not have pvc on your big list of killer and and that ok. it a pretty obscure and boring subject . when i be flip around and saw this title on hbo the first thing i think be ohh . blue vinyl and think i might see some skin . instead and after a few second and i realize this be a documentary . me and be the glutton for bore subject matter and decide to watch it . while it be a little one side and it give an overall impression of the positive of convenience and the negative of pvc and give both oppose argument from the industry and activist range from the end user ( her parent ) to the ultra hippie to the corporate exec . while the narrator do give an impression of her own view and it isn not to the point that disallow the viewer to still disagree easily while and that a nice thing to have . i love the shot of people concern with this issue go out and test the air themselves and i like how all involve be calm and overall respectful and and i most like the opposition between the narrator and her parent . it really bring it down to home the cost issue and unavailability of other material be slightly anti climatic and but give a good feeling of what really go on . good documentary . positive maybe not ready for mainstream and but demonstrate excellent promise . a more famous documentary maker could learn a thing or two from this girl .
