Had been meaning to see this for quite awhile. Parts were rather dated; other parts were eerily prescient. I am not quite sure who the presenter was supposed to be--random hired bloke?--why didn't the filmmaker do it? (I just looked him up--apparently Barry Zwicker is an alternative media journalist--I think it still might have been helpful to identify his credentials as not everyone would know who he is).
Anyway, it wasn't quite as polished as I was expecting, but you can't really fault the basic message. My viewing cohort had some issues with their analysis of alternative energy sources; and I have to say that I wasn't sure why they spent the whole movie saying that nothing would be sufficient to replace oil and natural gas (not solar, not wind, not anything), but then in the last 5 minutes they started 'ra-ra'-ing alternative energy.
