amazing film . i guess we all know that our way of life be base on energy and that energy in large part come from oil . ( a very large part ) i be not much for write review and and i be not very good at it and but what an amazing documentary . no sledgehammer over the head and just expert in the oil industry and other field and talk about the upcoming oil peak . i think we all know how dependent we be on oil and but it take something like this film to hammer the point home . anyhow and enough blather from me and rent and buy or view this film . it be very important that people understand this issue . ( i list this comment a amay contain spoiler for those that think there be no oil crunch come ) .
